The UK band McFly has names for the relationship between the band members. Danny Jonas and Tom Fletcher is known as Flones and Dougie Poynter and Harry Judd are known as Pudd. Fans of Mc Fly are known as Galaxy Defenders, Star Girls, and Mc Fans.
Similarly One Direction, the biggest band in the world at the time, and their sister group Little Mix have a lot of this. The romance between 1D Zayn and LM Perrie is labelled Zerrie by fans, whilst Jade and Harry's friendships are called Jarry. Within the groups, Leigh Anne and Perrie are called Lerrie, Jade and Perrie are called Jerrie, Jade and Jesy are called Jadesy, Jesy and Perrie Pesy, Leigh Anne and Jesy Lesy, and Leigh Anne and Jade are Jeigh. For 1D, Zayn and Louis are nicknamed Zouis.
The MAFIAA (Music And Film Industry Associations of America) - "Affectionate" collective nickname for the RIAA and MPAA, which have many members in common and have much of their agendas in common. Used a lot on Slashdot.
Similarly, the RIAA Spanish equivalent, the SGAE, had gotten the backronym "Siempre Ganamos Algunos Euros" (We Always Earn Some Euros). When La Frikipedia, one parodic wiki, was demanded by honor reason by the aforementioned entity and forced to shut down just because people edited the article about the entity to show them in an allegedly unflattering way, another parodic wiki rescued the article and renamed it as "La Innombrable" (The One Who Must Not Be Named), in a mock intent to avoid legal problems and also furthering the comparison between them and the villain of a certain famous book series about wizard kids.
Fans of Owl City tend to refer to Lights as the female-Owl City, and vice-versa.
The Area - while not a nickname for David Bowie, per se, it is the fan name for a certain bodily appendage of his that is best left unmentioned on this page and taken to Memetic Mutation levels regarding its appearance in Labyrinth. It now has a religion, Areaology.
The Dame — A nickname for Bowie himself in the British music press; dates back to The Eighties and the height of his mainstream success and was initially used as a putdown (according to journalist Charles Sharr Murray) . Likely inspired by the "Dame" character in British Pantomime, who is a comic old woman played by a beloved, famous Large Ham male performer in drag.
Disco? Very! - Electric Light Orchestra's album Discovery. One listen to "Shine a Little Love" or "Last Train to London" should show you exactly how it got this name. May also be applied to the Daft Punk album of the same name, for similar reasons.
With the Daft Punk album, the wordplay is entirely intentional from the start, and it also serves as a Stealth Pun - DP explained that they chose the name after their memories of listening to music as kids (which obviously included disco).
Beyoncé is often referred to as Beysus by her fans because she's like well...Jesus to them.
Silver - Starflyer 59's officially self-titled debut album, after its monochromatic silver cover (also in reference to their sophomore album, the also-monochromatic Gold). This caught on with the band and the record label, and was used as the official title when the album was rereleased with bonus tracks.
This set a standard for various other self-titled albums with one-colored covers: Metallica's 1991 self-titled album is called The Black Album and Weezer's three self-titled albums are called The Blue Album, The Green Album and The Red Album in respect to chronology.
Which is confusing given that 1962-1966 and 1967-1970 are often called The Red Album and The Blue Album.
John calls him Paulie in the cartoon episode of "I Feel Fine."
Sir Paul: what the British media, and those following their lead, call Paul McCartney. When he was knighted, he accepted the title but made public that he didn't want to use it; MPL had other ideas.
"Macca" is also used at times.
Johnny: affectionate nickname for John Lennon, usually reserved for Fanfic. At least as old as Elton John's "Empty Garden."
Note that "Johnny" and "Paulie" may be used separately from or in conjunction with "Georgie" and "Ringsy".
Saint John, Martin Luther Lennon: names for Possession Sue versions of John.
Paul in pain: a Hurt/Comfort Fic starring Paul McCartney. First used in a magazine review of Run Devil Run ("Paul in pain gets back to where he once belonged"); popularized by Ms. Moonlight on her Indica's Attic Fan Fic site when she used it to describe its contents. "X in pain" has been used for other Beatles as well.
The Fifth Beatle: Many people, but most commonly George Martin, who served as Record Producer for every album of theirs save one and is recognised as playing a key role in helping them achieve their musical vision.
"Old man Paul", "old man Ringo": the surviving Beatles as they exist today.
Faul: Post-'66 Paul, to proponents of the "Paul is Dead" theory (amalgam of "false" and "Paul").
Smell the Glove - Actual title of Spinal Tap's real/fake album (with an all-black cover). Often used ironically to refer to Metallica's self-titled fifth album, also with an all-black cover (either the last "good" or first "bad" Metallica album, depending on who you ask).
The Black Album is also used to describe the same album in a less negative manner.
"Cletus" - A derisive term used to describe backup dancer/rapper/actor Kevin Federline, in reference to the Slack-Jawed Yokel from The Simpsons. By extension, his ex-wife Britney Spears has jokingly become known as "Brandine" to some in the wake of her Freak Out after their divorce.
"Fed-Ex" is another term for him.
Don't forget "K-Fed".
Led Zeppelin IV - much like the previous White Album example, near-universally used to refer to Led Zeppelin's symbolically titled fourth album.
Also commonly known as ZOSO, after one of the aforementioned odd symbols.
Which is in itself ironic, because Page has repeatedly stated that ZOSO is not intended to be pronounced as a word.
"The Object" for the black motif on the 'Presence' album artwork
"Zep" or "Led Zep", for the band. "The Hammer of the Gods", borrowed from a lyric in "Immigrant Song", later became the title of a biography.
Apparently there are nicknames for the rest of the members. Drummer John Bonham was affectionately known as "Bonzo," Jimmy Page is "Pagey", Robert Plant is "Percy" (I have no clue why), and John Paul Jones is "Jonesy" (which is actually very handy when you have to differentiate him from the other member named John).
Their album 'Coda' has a drums-only track entitled "Bonzo's Montreux."
The band as a whole has recently been dubbed "Loop Zoop" by the Tumblr fandom due to Memetic Mutation of a 4Chan post where someone talked about being high from dental medication, repeatedly trying (and failing) to search Led Zeppelin on YouTube, and finding "Loop Zoop" written over twenty times in his browser history the next day.
No-Talent Ass-Clown - Michael Bolton, thanks to a quote from an unfortunately named character from Office Space. When asked why he doesn't just go by "Mike", he responds with, "Why should I? He's the one who sucks!"
John Deacon of Queen is often (affectionately) referred to as 'Deaky'.
While "The Guv'nor" refers to Brian May (the appellation came before the song).
The Artist, TAFKAP - Prince; during the period where he changed his stage name to an (intentionally unpronouncable) symbol because his old record label held the rights to "Prince", the media and fans eventually settled for referring to him as "The Artist Formerly Known As Prince".
Akka-Dakka: Australian nickname/pronounciation for AC/DC.
Although only really known within the fan community, the heart-eyed dinosaur on the cover of Lemon Demon's "Dinosaurchestra" album is typically referred to as Goodsie, after a very strange dream had by one of the community members.
Van Horrible - same as above, when Gary Cherone replaced Sammy Hagar.
For the bandmembers, "Diamond Dave" and "DLR" for David Lee Roth, and "The Red Rocker" for Sammy Hagar.
"Wacko Jacko" for Michael Jackson. Granted it's a mean tabloid name but who HASN'T called him that at some point?
His famous dance move (where he glides smoothly across the floor backwards), was nicknamed the "moonwalk" by the media and not by Jackson himself, but when he made his 1988 anthology film Moonwalker, Jackson did choose the name for the movie (all according to The Other Wiki).
"The Gloved One", after the trademark single white glove he wore during the 1980s.
He was also called "The Thriller", especially back in the '80s. When he was part of the J5 he was some times called "Little Michael" by fans.
"The King of Pop" is an odd case in that it was Jackson's handlers who pushed it into common usage rather than his fans or the press, supposedly creating the nickname because Jackson was jealous that Elvis Presley had the nickname "The King". Fox and MTV had to agree to use the phrase if they wanted to air videos from Dangerous in 1991; rumors flew that the VJs on the latter had to use it whenever he was mentioned. While Jackson's fans and his publicity machine still use this one unironically, in his final years it was common for entertainment journalists to qualify it as "self-proclaimed King of Pop".
James Brown, the "Godfather of Soul", "Soul Brother #1" and "The Hardest Working Man in Show Business."
Perhaps in reference to the above, Mary J. Blige has been called the "Queen of Hip-Hop Soul".

Tim "Ripper" Owens is known by some of his fans as The Man of a Thousand Bands due to his relatively large number of projects he's worked on (and been fired from.)

He lampshaded his tendency to get fired from bands to make room for old vocalists in an interview with That Metal Show, first by joking that he started his solo project so he could have a band he couldn't be fired from, then by joking that his solo band tried to fire him.
Frank Sinatra - "The Chairman of the Board" and/or "Ol' Blue Eyes."
Disturbed's Mascot, officially known as "The Guy", has been dubbed Morbus by the fanbase (Latin for "Sickness").
American thrash revival band Municipal Waste go by the nickname "The 'Waste".
The band members of X Japan have a few: Yoshiki has been stuck with "Yo-chan" (after what his biggest fan called him), "Yoyo," and the not-quite-flattering "Pony" (because some people say his face reminds them of a pony.) hide is often called "Pink Spider," again after a name Yoshiki called him due to his wild pink hair, that he referenced in his last song. Sugizo is occasionally referred to as Sugi.
Also, Yoshiki referred to his same certain bodily appendage as a 'rocket' in a couple of songs, and it got picked up by fans. It Gets Better for those into Ho Yay (or the occasional cheap laugh). hide, the late guitarist, wrote and performed a song called "Rocket Dive" and once drunkenly yelled in an interview "Rocket dive to my spread beaver!" He was talking about his song and his solo band....

Anna Nalick's fans know her, and constantly refer to her, as AnNa (a contraction due to the fact that the second and third syllables of her name are the same). Interesting in that she originated the nickname herself, making this something of a case of Memetic Mutation. Anna's other nickname, also used frequently by both fans and Anna herself, is "The Lullaby Singer", which is the title of her first comeback single.
Alice in Chains' self-titled final album, which has a picture of a three-legged dog on the cover, has been referred to by such names as Tripod and Lucky (based on an old joke about a three-legged, one-eared, one-eyed dog named "Lucky").
