* Music/TheBeatles fans vs. Music/TheRollingStones fans. More rabid feuders are often surprised to find out that the two bands were actually close friends with one another and would occasionally drop in on the others' recording sessions. At least two tracks, the Beatles' "All You Need Is Love" and the Stones' "We Love You", featured members of the other group providing background vocals.
** In fact, the Rolling Stones were signed because the Beatles were impressed by their talent and recommended them to Dick Rowe (infamously the man who passed on signing the Beatles), and even gave them a song they wrote, "I Wanna Be Your Man", which the Beatles recorded after.
*** Also between Stones fans who prefer the Brian Jones years or the Mick Taylor years.
* Music/MichaelJackson fans vs. Music/{{Prince}} fans. Many of Michael Jackson's more "mainstream" fans decry Prince as a vulgar womanizer, while many of Prince's more hardcore fans view Michael as perhaps a formidable singer, but an overly commercialized one who relied too much on other musicians for writing, playing, and studio craft.
** If discussions under news articles about him are any indication, Jackson fans also are embroiled in ''nasty'' rivalries with fans of Music/ElvisPresley and/or Music/TheBeatles with regards to the title of Greatest Musician(s) of All Time. Jackson fans call Presley a thief of black music who didn't even write his own material, and slam The Beatles as both dated and less talented than Jackson, since they didn't dance or put on giant stage shows. They also claim that the press has unduly favored these acts and been willing to overlook their personal flaws because they were white (a claim ''Jackson himself'' made in 2002), and argue that ''everyone'' in the world knows Jackson's music. On the flip side, Beatles fans aren't too happy that Jackson made and spent quite a bit of money off of the band's work once he acquired the rights to the ATV song catalog in TheEighties and (similar to the Prince rivalry) did far less of his own writing/playing. That both Presley and The Beatles were far more prolific than Jackson (and in a much shorter time frame than him in the case of the latter) doesn't help.
* Music/JudasPriest vs. Music/IronMaiden.
* Music/GunsNRoses vs. Music/StoneTemplePilots tends to breed epic level shitstorms [[FanDumb among a certain portion]] of the Velvet Revolver fanbase. The [=GnR=] camp tends to be filled with Purists, Willfully Blind, and Strawstuffers who view the original Guns 'n' Roses as gods and see Scott as an [[LargeHam overly-hammy]], AmbiguouslyGay ReplacementScrappy for Axl and blame Scott for Velvet Revolver not being the same as the old [=GnR=] (despite the fact that Slash ''wanted'' someone who was different). STP fans are usually [[FanDumb Toxic Geniuses, Highbrow Elitists, or Misplaced Champions]] that instantly retaliate with similar insults at Axl and will attack Guns n Roses as overblown hair metal crap that remains popular solely due to the 12 year-olds that only know of Slash from ''Guitar Hero'', and will go on about how there's no appreciation for Scott because STP is too sophisticated for [=GnR=] fanboys.
** It's to be expected when a grunge singer joins a band with members of a Hard Rock group.
** This doesn't even take into account the fandom rivalries that exist for literally every musician to ever pass through GNR. The main one, of course, is Axl fans vs Slash fans, but there also exists indivdual fandom rivalries between every guitar player (the biggest being Slash fans vs Buckethead fans), every drummer (still mostly revolving around Adler fans vs Sorum fans, even though most will admit there have been some incredible replacements for both men), Duff fans vs Tommy Stinson fans (which is probably the least vitriolic of any), pre-1991 fans vs post-1991 fans, pre-Slash fans vs post-Slash fans 2001/2 fans vs 2006 fans, 2006 fans vs current (2011) fans...and on and on and on and on...
* Music/XJapan vs. COLOR / Music/DynamiteTommy. The bands themselves were rival bands, and though the drama mostly died down between them, the fans still sometimes won't let it die.
* Music/XJapan vs. Music/DirEnGrey is a bit more modern of one, with some Diru fans becoming vocal {{Fan Hater}}s toward X fans.
** And Music/DirEnGrey fans vs. Music/{{Kuroyume}} fans. Their respective fanbases argue about which band was really responsible for kickstarting the Eroguro kei sub-movement and popularizing AvantGardeMetal in VisualKei. Some Kuroyume fans even go as far as claiming that Dir en grey copied their aesthetics, sound, and manner of performance, while Dir fans deny these facts and even claim that they perfected Eroguro by themselves.
*** Bonus points for referencing the Music/{{Pantera}} vs. Exhorder FandomRivalry or explicitly throwing it in. [[note]] Just like with Pantera and Exhorder, the members of Kuroyume and Dir en grey are friends. [[/note]]
* Music/XJapan has a few of these internally as well. The longest-running had been hide vs. Toshi. [[{{Shipping}} Various]] [[FanDumb factors]] [[FandomBerserkButton somehow]] [[YaoiFangirl joined]] [[ScamReligion in]] [[BrokenBase a]] [[InternetBackdraft confluence]]. [[{{Shipping}} Shippers]] had long seen hide and Toshi as rivals, some [[WordOfDante unofficial information]] hinted that they had some sort of rivalry or hate toward each other, and once the band broke up it entirely exploded. Some hide fans blame Toshi for breaking up Music/XJapan in 1997 due to his joining a [[{{Cult}} new religious movement]], and some Toshi fans do as well - but the hide fans who believe so believe the breakup and loss of success contributed, in some way, to hide's [[OffTheWagon downward spiral]] into [[TheAlcoholic alcoholism]] and eventual death. Cue much hatred for Toshi among hardcore hide fans. Considering that some [[FanHater hardcore Toshi fans]] and/or Yoshiki/Toshi shippers blamed hide for the band's breakup, saw hide as an intruder on Toshi and Yoshiki, and believe him to have who intentionally suicided to make Yoshiki hurt... you can just imagine what happens when these groups meet up. There's a reason it's called the Legendary FlameWar, and a reason why mentioning certain claims (e.g. calling Toshi a brainwashed cult member until 2010 when he admitted he had been, saying hide's death was intentional suicide aimed at punishing Yoshiki) will lead to sane fans piling on to quench an InternetBackdraft. This FlameWar got possibly the best dousing any FlameWar could, though, once Toshi ''did'' leave [[ScamReligion HomeOfHeart]] and confessed to having been brainwashed for over 10 years - and rekindled his friendship/relationship with Yoshiki. Occasionally one side will still try to start drama from it related to their still-ongoing hatred of hide and the rumors about him, but it's pretty much out now for very good reason.
** Taiji vs. Heath for best bassist. This can get a Website/YouTube comment section on FIRE. That said, it somewhat lessened as Taiji [[AuthorExistenceFailure can't replace Heath anymore.]], then picked up again when DeadArtistsAreBetter began to take effect for Taiji.
** Another X one that started recently sprouted from the BrokenBase that happened as a result of 2008 Cancelwank. A small contingent of enraged X fans suddenly hated Yoshiki and began to bash him, instead announcing their support for ex-bassist Taiji [[FandomBerserkButton and saying the band ended in 1992]], [[MisaimedFandom who they held up as some kind of hero of rock and roll who "knew how bad Yoshiki was all along."]]. Unfortunately, these fans forgot that Taiji and Yoshiki have somewhat reconciled. This one has gotten a fresh shot of gasoline due to NeverSpeakIllOfTheDead related to Taiji.
** Old fans vs. new fans, homophobes who somehow got into the band anyway vs. [[YaoiFangirl Yaoi Fangirls]].... this fandom has enough internal rivalries to keep the flames roasting for years.
* Music/{{Galneryus}} vs. Music/DragonForce Nearly EVERY Galneryus video will have comments either accusing the band of being a bad copy or some sort of debate over whether Galneryus or Music/DragonForce is better just because both bands play a fast paced form of power metal.
** YAMA-B VS. Ono can light a flamewar up pretty fast. Original vocalist from the beginning vs. ReplacementScrappy with a love for AutoTune.
** Old Galneryus vs. New Galneryus.
* Try finding ANY power metal video with a decent number of views and without an argument between people who dislike [=DragonForce=] (generally displaying a level of ignorance that belies a complete lack of knowledge of them past having played ''VideoGame/GuitarHero'') and fans.
* Gangsta Rap Fans/Alternative Rap Fans/Hardcore Hip-Hop Fans/Political Rap Fan vs. Pure Mainstream Rap fans. Is also an example of a BrokenBase. There's also other deeper socio-cultural issues involved.
** Music/{{Nas}} fans vs. Music/{{Jay-Z}} fans is arguably a microcosm of this rivalry.
** Likewise with Music/{{KRS ONE}} fans vs. Nelly fans.
* Music/TupacShakur fans vs. Music/TheNotoriousBIG fans. Which is weird considering how different their music is. One's a Rebellious quasi-political activist, The latter's a new york mafioso. It's like comparing Huey P. Newton to Al Capone.
** They became FriendlyFandoms years later, when DeadArtistsAreBetter took effect.
* Ludacris or T.I.
* Music/JimiHendrix fans vs. Eddie Hazel/Ernie Isley fans.
* Music/RedHotChiliPeppers fans vs. Music/FaithNoMore fans.
** Though not as big as the above, there's also {{Wolfmother}} fans vs. fans of pretty much any MikePatton project: It can all be traced back to [[http://www.youtube.com/watch?v=THV23g3z5qU one interview with Patton]].
* Music/AliceInChains fans vs. Music/{{Nirvana}} fans. Which is odd because the former was predominantly [[Music/HeavyMetal metal]] while the latter was mainly influenced by HardcorePunk.
** And to a lesser extent, Alice in Chains fans vs. Music/{{Soundgarden}} fans.
** Hell, Alice in Chains fans vs. fans of any other {{Grunge}} band.
*** Most of it seems to come from the metalheads that are common in AIC's fanbase, who resent grunge and the fact that the band is associated with the genre. Most of them also tend to enjoy Soundgarden though.
* Metalheads vs. [[strike: Nu-Metal]] ''ANY'' Metal offshoot.
** Be it NuMetal, GrooveMetal or {{Metalcore}}, almost all modern, popular metal bands have this in their fanbase amongst each other (Music/{{Slipknot}}, Music/{{Disturbed}}, Music/AvengedSevenfold, Music/LambOfGod, Music/{{Mastodon}}, Music/KillswitchEngage, etc.) usually fighting over who has the best guitarist/bassist/drummer/singer/band. Considering the persecution they get from the "true" metalheads, you'd think they're learn to stick together (also most of these bands are friends).
** Metalheads vs. rappers. Although it's slightly one sided, as most rap fans either don't know much about metal or aren't too concerned with the rivalry. But type "metal vs rap" on [=YouTube=], and you'll get tons of videos of mostly one sided biased debates of why metal is better than rap, usually by insecure and/or ignorant metal fans who haven't heard any hip-hop outside of Top 40. The artists themselves don't seem to bicker as much as their fandoms, however, considering the cross-pollination between the two genres and numerous collaborations.
** Metalheads vs. pretty much everyone else, really.
* Bizarrely and hilariously, German Music/TokioHotel fans versus French Tokio Hotel fans. Severe internet-based catfighting is involved.
* Music/{{Megadeth}} fans vs. Music/{{Metallica}} fans. The longest feud in the history of Music/HeavyMetal.
** This stems from the fact that early on in Mustaine's career he genuinely despised the other band as they kicked him out without warning, they always overshadowed his accomplishments, and he believes the majority of their first two albums are his work. They've mellowed out over the years, even touring briefly together in the 90's but Mustaine still feels somewhat bitter about not getting a second chance.
*** And now, the bands are touring together... with Music/{{Slayer}} and Music/{{Anthrax}}.
*** And while we're on that subject of Anthrax, don't get the fans started on Joey Belladonna vs John Bush.
* On par with the Metallica vs. Megadeth feud... We have DeathMetal vs. BlackMetal.
* The Dillinger Escape Plan vs. Ion Dissonance. The "Metallica vs. Megadeth" of metalcore.
* Gojira vs. Meshuggah. The "Metallica vs. Megadeth" of technical death metal.
* TLC fans vs. SWV fans, superficially similar in that they were 2 trios of urban/R&B singers. Though TLC was/is considered more edgy, and more popular.
** On occasion people (specifically ''[=VIBE=]'' magazine) would throw in the group Jade for good measure. Which was basically a HotterAndSexier version of the two aforementioned groups. They lasted only 2 albums though.
* Music/{{Sade}} fans vs. Anita Baker fans.
* Music/MariahCarey fans vs. Music/WhitneyHouston fans.
* Music/InsaneClownPosse fans vs. Music/{{Eminem}} fans.
* During TheEighties there was Music/{{Madonna}} vs. Music/JanetJackson vs. Music/PaulaAbdul vs. Jody Watley fans
* Music/NewKidsOnTheBlock vs. New Edition (for obvious reasons)
** Repeated with the Music/BackstreetBoys vs. Music/{{NSYNC}}. In some parts of the internet, the fans still fight over who was better.
*** And 'twas done in ''WesternAnimation/CelebrityDeathmatch''.
* Creator/{{Motown}} vs STAX/VOLT
* Music/{{Blur}} fans vs. Music/{{Oasis}} fans. It even caused marriages to break up. Or so the British tabloids would have us believe.
* Music/{{Radiohead}} fans vs. Music/{{Muse}} and Music/{{Coldplay}} fans. Still goes on after over ten years. Radiohead fans think that both of the other groups are only famous because they copied the two poles of Radiohead's pre-''Kid A'' style (Muse copying the rockier songs, Coldplay the ballads) after Radiohead stopped doing mainstream rock.
* Music/{{Slipknot}} fans vs. Music/{{Mushroomhead}} fans.
* On the note of Music/LimpBizkit, Zakk Wylde of Music/BlackLabelSociety outright despises Durst. In [=BLS=]'s live album ''Alcohol Fueled Brewtality'', Wylde shouts in the middle of the intro for ''Super Terrorizer'' "Limp Bizkit sucks dick!". In the Ozzfest 2001 live album, he shouts in the middle of [[http://www.youtube.com/watch?v=I6lOtQi15MU the song's]] guitar solo "Limp Bizkit ''still'' sucks dick!".
* The "Mods vs Rockers" youth gang rivalry was based both on lifestyle and musical choice. The macho rockers enjoyed rock and roll from artists such as Music/ElvisPresley, while the sophisticated Mods followed more blues-based rock such as The Who. Clashes between gangs of mods and rockers became quite notorious during their heyday, especially at Brighton Beach. This was perhaps most memorably portrayed in The Who's rock opera and film ''Music/{{Quadrophenia}}''.
** None other than Music/TheBeatles spoofed the rivalry in their film ''Film/AHardDaysNight'', when a reporter asks Ringo if he is a mod or a rocker. Ringo answers, "I'm a mocker."
* Music/SexPistols vs. Music/TheRamones. [[TakeAThirdOption or]] Music/TheDamned, Music/TheClash, Crass or Stiff Little Fingers
* Punk vs. Metal, or Punk vs. Prog Rock, that was more vitriolic
* Music/BoneThugsNHarmony fans vs. fans of every other Midwestern rapper with a similar style as bone. Particularly Twista, Do or Die, and Crucial Conflict. Most of this started because bone was dissed by the aforementioned groups. The artists themselves has killed the rivalry, but some of the fans are still kinda sore about it. Interestingly enough the aforementioned groups more or less shared the same fan base.
* Music/{{Mastodon}} fans vs. Music/DreamTheater fans vs. Music/SymphonyX fans.
** Occasionally Music/{{Opeth}} fans have been known to get into the fray as well.
* Newer country music fans who would like to see their genre have a return to public prominence if it means shedding some old bonds, versus traditional country music fans who would like to see Music/TaylorSwift's head on a stake. Taylor's clean sweep of the [=CMAs=] and [=AMAs=] in the fall of 2009, combined with the outpouring of support from the Music/KanyeWest incident and a critically praised ''Series/SaturdayNightLive'' hosting, have led to a massive backlash from the country music community at Taylor's media oversaturation.
* Music/TheNotoriousBIG fans vs. Music/{{Jay-Z}} fans. which got over shadowed by the 2Pac vs. Biggie situation.
* Music/{{Buckethead}} vs. [[Music/GunsNRoses Slash]], due to Buckethead taking Slash's position in Music/GunsNRoses. The general assumption made is that while Buckethead has more technical skill, his music has 'no emotion'. Of course, those people [[http://www.youtube.com/watch?v=YfYYRRJxPk0 haven't ever really listened to Buckethead]].
* Music/{{Helloween}} vs. Music/GammaRay
** Now the bands even tour together.
* In classical music, there's early music fans ("after Bach, it all sucks") vs. those who prefer the classical/romantic "canon" ("after Brahms/Strauss/Wagner, it all sucks") vs. 20th/21st century music fans ("but there's a lot of really good classical music being written today! and composers have more freedom now!") And within contemporary classical music, there's the debate between fans of the more atonal genres (such as serialism), the more tonal genres (minimalism and neo-Romanticism), and those who fall between the two extremes.
* K-pop vs. J-pop in general, but Johhny's Entertainment vs. SM Entertainment in particular. Basically, a extended, wanky debate over which boyband has more ''talent''.
* Since Music/BobDylan and Music/TheGratefulDead toured together in 1987 there has been some uneasiness between their fans. Deadheads generally like Dylan, but many Dylan fans considered the Grateful Dead and their fans to be pathetic hippies jumping on a legend's bandwagon. A lot of this has been defused since Dylan himself acknowledged that performing with the Grateful Dead helped rejuvenate him artistically, he's covered Dead songs in concert, he's adopted their "never play the same setlist twice" concert format, and he co-wrote the songs on his ''Together Through Life'' album with Grateful Dead lyricist Robert Hunter.
* The Four Tops fans vs. The Temptations fans, is probably the UrExample of fan rivalry.
* Death Row Records fans vs. Ruthless Records fans
* Similarly No Limit Records fans vs. Cashmoney Records fans. They were both from New Orleans, but musically different. No limit had a military/GangstaRap motif, where as Cashmoney helped usher in the whole materialistic GlamRap thing with a type 2 variant of GangstaRap.
* Music/TheWho vs. Music/LedZeppelin. Generally boils down to which individual members were the "Greatest of All Time" on their respective instruments. Other issues include which band was more influential and who was truly the best live.
** Probably stems from Keith Moon and John Entwistle declining Jimmy Page in recreating The Yardbirds as a supergroup before Led Zeppelin was even around.
* The famous Music/NewWave rivalry was Music/DuranDuran and Music/SpandauBallet, even though there wasn't really a great amount of enmity between the bands themselves.
* Back in TheThirties and Forties, it was Jazz Benny Goodman fans vs. Artie Shaw fans. They were both talented clarinetists who led big bands and made an effort to undermine the segregation in the music industry. Goodman was the "King of Swing" while Shaw was the "King of the Clarinet" (amusingly enough, Shaw thought it should be the other way around. He believed that Goodman was a better player but was limited by his use of arrangements rather than original compositions).
* Music/KateBush fans vs. [[Music/ToriAmos Tori]][[FanCommunityNickname philes]]. It's normally one-sided. Many Tori fans like Kate, but Bush fans often bitch about Music/ToriAmos being a "rip-off" of her.
* Mostly within the Music/{{Genesis}} fandom, Music/PeterGabriel vs. Music/PhilCollins. Quite the case of FanDumb, as both are friends, respect each other greatly as artists and continued to work together for years after Peter Gabriel left Genesis, with Collins contributing spectacular drumwork on many of Gabriel's solo albums (and being stunned by the quality in the process, joking Gabriel had been holding back his best material for his solo career) and Gabriel himself stating that Collins sings Genesis's songs better than he did. (Objectively, Collins does have a better vocal range, though Gabriel is more creative and experimental, so it balances out.)
* Music/BritneySpears fans vs. Music/ChristinaAguilera fans. It has gotten so bad that some Britney fans ''attacked Music/{{Sia}} directly on Website/{{Twitter}}'' simply because she collaborated with Christina. Christina fans retaliated by trolling Britney forums thoroughly.
** Or both fandoms versus the [[Music/LadyGaga Little Monsters.]]
* The fandoms of Music/TheProtomen and Music/TheMegas seem to have a somewhat heated rivalry, despite the two bands getting along fairly well. Most likely due to the fact they share the same [[VideoGame/MegaMan base inspiration]], even if they go in [[DarkerAndEdgier two]] [[RockOpera wildly]] [[CoveredUp different]] [[VillainSong directions.]]
* Music/LadyGaga fans vs. Music/{{Madonna}} fans. It's odd, considering that Gaga & Madonna are friends in real life.
** At this point it seems like every musical fandom versus Music/LadyGaga's.
* Music/LadyGaga Vs Everyone
** Pretty self explanatory, read her page for more.
* [[Music/LadyGaga Little Monsters]] Vs [[Music/BritneySpears Cheetolings]]
** Which is strange because both Britney and Gaga love each other and have worked together three times in the past. Both are inspired by each other and Gaga is Gaga due to Britney in some part.
* [[Music/BritneySpears Cheetolings]] VS Everyone
** With complete disregard of how Britney has never said anything bad about anyone outside of the year 2003 and 2004, about Christina Aguilera after years of hassling and mud slinging from her and her fans...and even then it was polite.
* [[MeleeATrois Rock vs. rap vs. country]] In the 90s, no teenager was into country.
* Any female popstar's fanbase will inevitably be at odds with another's.
* Old school Music/{{emo}} (Rites of Spring, Moss Icon, etc.) fans vs. new "emo" fans. The new emo fans had an advantage, what with getting mainstream coverage and VASTLY outnumbering old school emo fans (and probably listening to music released in the [[TurnOfTheMillenium same decade]] ). Then the new emo fad ended.
** Generally, fans of old-school emo don't even consider the newer music being called "emo" to really be emo at all because it's perceived to be so far removed from it sonically. Other titles, like PopPunk and {{post-hardcore}}, are more often used. The same debate rages on about the "screamo" subgenre. On the one hand, you have bands like Circle Takes the Square, Saetia, and Hot Cross. On the other, Underoath and (at least) early Hawthorne Heights.
* Fans of R&B/Pop stars vs fans of more "pure" and "mature" R&B/Soul ''vocalists'' artists. This goes as far back as the Motown vs. STAX/Volt rivalry of TheSeventies. The modern version of that rivalry basically boils down to fans of artists like Music/{{Rihanna}}, Kristina Debarge, Mya, Nicole Scherzinger, Christina Milian, Ashanti, Chris Brown, Kerri Hilson, etc vs. fans of artists like Anthony Hamilton, Leela James, Amel Larrieux, Kem, Conya Doss, Vivian Green, Music/JillScott, Angie Stone, Goapale etc. The fans of the former group of artists thinks the latter artists' style is outdated and boring, and their fans are a bunch of out of touch elitist. The later usually calls the former group of artists "''Industry Whores''" whom along with the record companies are [[MusicIsPolitics impeding the success of the latter]], as far as fans of the former group goes the latter don't think much of them at all, usually because they think they're all a bunch of prepubescent dumb girls. If some of the former group of fans happens to be actually ''older'' (basically 20 to 30 somethings), then the latter fans' opinion of them is even ''lower''.
** Artists like Music/AliciaKeys, and Music/MaryJBlige can be kinda dicey as to what group they fall into. Most believe their work falls somewhere in between. Especially Alicia, her last two albums seems to be intentionally straddling the fence. Going from R&B/Soul to Power pop ballads, which eventually led [[BrokenBase to her base breaking]].
** In some cases the fans of the "mature artists" think that the pop stars are only where they are because of ButNotTooBlack, because many of the pop stars (e.g. Beyonce, Rihanna) are lighter skinned. For example, Music/IndiaArie fans feel that Music/AliciaKeys won the Grammy over Arie in 2002 because of her skin color.
* In the avant-rock community, there's Music/FrankZappa vs. Music/CaptainBeefheart. Doesn't help that the two had a love/hate friendship while they were still alive.
* Music/{{Garbage}} vs. Music/{{Curve}}, though mainly it exists solely on the Curve side. Fans of Curve absolutely hate Garbage, thinking of them as "manufactured" and a revenge plot cooked up by Butch Vig after the group rejected an offer by Vig (who was a fan of the group BTW) to work with them on an album.
* If [=YouTube=] comments are believed, Music/JustinBieber fans and fans of every other music genre.
** Though Justin Bieber fans and Jonas Brothers fans have a particularly nasty rivalry going.
* Post-2005 Music/{{Nightwish}} or Tarja Turunen's solo career. You aren't allowed to like both.
** Nightwish has also seen tension with other genres of metal, mostly due to its atypical style compared to the typical "metal" band. Unfortunately, a large portion of hate comes from [[HeManWomanHater misogynistic macho-metalheads]] who think that [[StayInTheKitchen female vocalists don't belong in a metal group]].
* In general, {{Grunge}} fans vs HairMetal fans. According to a sizable group of fans from both genres, you're not allowed to like both -- even though active rock stations typically play both. Although, both groups are in agreement over not liking {{post-grunge}}.
* Music/YokoKanno vs. Music/YukiKajiura, both among the most acclaimed composers for Japanese anime and Japanese films and both have their dedicated followers. Kanno fans argue a vast and versatile style and a [[CowboyBebop strong]] [[WolfsRain work]] [[VisionOfEscaflowne resume]] of [[Anime/GhostInTheShell shows]] is what makes Kanno a great composer, while Kajiura's iconic style and hit-and-miss history of [[Franchise/DotHack not]]-so-[[TsubasaReservoirChronicle great]]-[[ElementalGelade shows]] makes her a weak composer. On the flip side some fans who love Kajiura's savvy style will tell you Kanno is nothing more than a plagiarist.
** But of course, both sides have a healthy appreciation for both women.
* While [[FriendlyFandoms many fans enjoy both performers]], there is a growing rivalry between fans of Music/ProfessorElemental and fans of Music/MrBTheGentlemanRhymer.
* If you're a fan of Music/VanHalen, you MUST prefer either Music/DavidLeeRoth or Sammy Hagar. Liking both, or expressing no preference, is not an option!
** DLR fans will tell you that he's the ultimate showman and really brings the fun and passion, Van Hagar fans will say that Sammy has a better vocal range.
* East 17 versus Take That. The precursor to Blur v Oasis in Britain, East 17 were London hard-boys (their name comes from the postcode for Walthamstow) and Take That were northerners but seen as boys-next-door.
* Many Music/MileyCyrus fans tend to take a dig at Music/SelenaGomez. Ironically enough, Selena played Series/HannahMontana's arch-rival, Mikayla, in some episodes, prior to ''Series/WizardsOfWaverlyPlace''.
* [[ThreeChordsAndTheTruth Punk rock/new wave]] versus [[EpicRocking Progressive rock]].
** The rivalry even goes back to the embryonic stages of the genres: was the symphonic psychedelia of ''MusicSgtPeppersLonelyHeartsClubBand'' (Prog) the defining moment of late 1960s rock and roll, or was it the gritty minimalism of ''Music/TheVelvetUndergroundAndNico'' (Punk/New Wave)?
* With the long history of Music/FleetwoodMac, there's a certain amount of FandomRivalry going on between devotees of various incarnations of the band (not to mention individual musicians); the biggest distinction generally tends to be between fans of the early, hard-core BritishBlues Mac featuring Peter Green and Jeremy Spencer, and the post-1975 lineup featuring Lindsey Buckingham and StevieNicks. Paradoxically, given the long and fraught personal history between Buckingham and Nicks, there's very little serious FandomRivalry between the two; fans of one generally tend to like and appreciate the other (in contrast to professional rock critics, who in the 1970's and 1980's tended to line up in the Buckingham camp) simply because of the fact that both brought out the best of the other.
* White British R&B/Soul singer Lisa Stansfield fans vs her American counter part Taylor Dayne. Likely due to the fact that both have a somewhat similar vocal style and range. And secondly for being the only 2 white women to do R&B/Soul at the time
* Spanish Reggae vs. Reggaeton
* Music/{{Drake}} fans vs. Common fans. Also, to a lesser degree, Drake fans vs. Chris Brown fans, not helped by the fact that they both dated Rihanna. This one allegedly sparked an actual fight between the two at a New York nightclub.
* TheBirthdayMassacre fans vs. Black Veil Brides fans. See TBM's page for the explanation.
* Music/AphexTwin vs. Music/{{Skrillex}}, which is odd because Skrillex is a huge fan of and influenced by Aphex Twin.
** {{Deadmau5}} vs. {{Skrillex}}, which is also odd because the two are VitriolicBestBuds in real life.
* {{Dubstep}} fans vs. fans of every other [[ElectronicMusic EDM]] subgenre.
** And IN the dubstep fandom, Skream-influenced dubstep (e.g. Run Riot, Benga, Burial) vs. Skrillex-influenced dubstep (e.g. Flux Pavilion, Kill the Noise, Nero).
* {{Opera}} fans can get into RealLife arguments that make internet-based {{Flame War}}s seem polite. The biggest split is pro-Creator/RichardWagner vs. anti-Richard Wagner. Wagner fans cite his operas as being magnificently orchestrated, highly expressive, having intricate plots, and push the limits of singing ability to the max. Anti-Wagnerists claim that his operas are overly bombastic, histrionic, needlessly complex in terms of both singing and plot, and JUST TOO DAMN LONG.
* Music/TaylorSwift fans vs. Music/{{Adele}} fans — watch as Swifties cite Adele's music as being one-tone and Adele's fans accuse Swift's lyrics of being immature.
* Music/{{Ensiferum}} vs. Music/{{Wintersun}}. Started when Jari Mäenpää parted ways with the former to focus on the latter, kept going as Petri Lindroos has been seen as a ReplacementScrappy, and appropriately peaked when Wintersun finally released their much-hyped ''Time I'' after years of DevelopmentHell, while ''Unsung Heroes'' has been criticized for being a bit lackluster performance. All of this despite Jari himself stating that there's no bad blood between the bands, he's basically BFF's with Ensiferum's Markus Toivonen, and some Ensiferum members even made guest vocals on ''Time I''.
* Fans of KellyClarkson vs. fans of CarrieUnderwood argue on who is the greatest winner off of ''Series/AmericanIdol''. The rivalry got even more heated with pop singer Kelly's small forays into CountryMusic, Carrie's genre.
* Music/PinkFloyd: Roger Waters vs. David Gilmour vs. Syd Barrett.
* An example in K-pop is [[{{Music/EXO}} EXO]] vs. {{BAP}}. To add fuel to the fire, both groups were candidates for the MAMA 2012 rookie award.
* Indie fans vs. everyone. [[NoTrueScotsman Even each other.]]
* Music/SimpleMinds vs. Music/{{U2}}. People generally like to overlook the fact that Simple Minds' singer Jim Kerr and U2 singer Bono are actually good friends, and have even [[http://www.youtube.com/watch?v=zgg7NmzyfDQ performed together.]]
* LilKim vs. NickiMinaj. Two years after they wrote each other ReasonYouSuckSpeech /songs, their fans are still debating who's "fake"/"jealous"/"a sell out". To put it delicately.
* Recently, Music/LanaDelRey fans vs. Music/FlorenceAndTheMachine fans. Which seems quite odd since the two are friends and Florence even defended Lana's style and music in an interview, stating she loved it as well as the song "Video Games".
* In the [[{{Music/ACDC}} AC/DC]] fandom there's fans of Bon Scott vs. fans of Brian Johnson. However there's a large amount of fans that love both.
* Music/OneDirection have a few. For example Music/TheWanted. Members of the two boy bands got into a fight on Twitter once. This led to a fight between the Directioners and TWFanmily. It was pretty one-sided though, as the Directioners trounced over their rivals due to being much larger.
** Directioners vs. Swifties: When Harry started dating Music/TaylorSwift, the couple was downright hated by the Directioners. Even though the couple only lasted a few months, Directioners still show animosity to both Swift and her fans.
** Directioners vs. Rushers: The two boy bands were pitted against one another for a Kids' Choice Award, and while One Direction was always the favorite, Series/BigTimeRush was dominating the votes. One Direction still won, and Nick tweeted they got 63% of the vote. When 1D won, the top trend on twitter was the Directioners celebrating their victory, with the Rushers' trend stuck in second place.
** Directioners vs. Beliebers: The Beliebers are pretty much the only stan base at an equal level to the Directioners, so their fandom rivalry is probably the most legit.
* {{Queensryche}} Official fans vs Geoff Tate's Queensryche fans. So, so much. If certain members of these factions were to meet up in real life, the end result would likely involve several squadrons of riot police.
* LCDSoundsystem vs. Death from Above 1979. This rivalry started because DFA Records (full name Death from Above Records), the label of LCD Soundsystem frontman James Murphy, forced Death from Above 1979 (which had Death from Above as its name) to change its name. This battle can be defined as a draw, a result influenced by the fact that exist fans of both LCD Soundsystem and Death from Above 1979 and also by the SongAssociation: both bands appeared in the soundtracks of ''ProjectGothamRacing 3'' and ''SaintsRow2''.
* Danzig vs. Jerry Only. Danzig fans insist that Glenn should own Music/TheMisfits even though he officially quit the band in 1983 and refuses to work with them. Jerry Only fans are glad that Danzig is out of the picture and the band has actual production values in their current form. Danzig fans insist that Jerry is a total jerk, whereas on the flipside, Glenn has been caught lying in interviews, and his only recent blip in the media is getting punched out by the singer of another band.
** The video of that incident, which is floating around online, shows Glenn provoking the fight and throwing the first punch- which is the opposite of what Glenn claims happened. Going by Glenn's version, he was punched for no reason, however the actual footage show shim using a racial slur and throwing a sucker punch, only to get punched back in self defense.
* Music/KatyPerry fans vs. Lady Gaga fans: This rivalry has been expanded in 2013, when both singers released "Roar" and "Applause" on the same week respectively. Ironically, both singers are good friends, with the latter defending Perry's {{geisha}}-inspired performance at the 2013 American Music Awards, which sparked controversy as some critics accused the performance as racist and cultural appropriation.
* It was reported in Wired magazine's website that fans of Music/DoctorSteel were planning an "attack" on [[WebVideo/DoctorHorriblesSingAlongBlog Dr. Horrible]], by attending the Dr. Horrible panel at Comic-Con International in San Diego and openly asking questions on the floor of the panel about Dr. Steel, and spamming Dr. Horrible reviews and sites with links to Dr. Steel's website. No known reprisal was ever recorded.
