Refrain from Assuming is clearly an Audience Reaction — it's about listeners getting a song's title wrong based on the lyrics, rather than being an objective trope. Despite that, it's not indexed as YMMV. Thus, I'm proposing we rectify that by indexing it as YMMV, since most of the wicks, while not misuse, ought to go on YMMV pages (with a small amount of the examples I found already being listed on YMMV pages).

Of the wicks I checked, this is the tally:

• 36/51 involve songs being misnamed (though a lot of wicks are Partial Context Examples).
• 1/51 is an in-universe example (a character made the mistake instead of the audience).
• 8/51 are unclear as to whether they're about mistaken guesses.
• 3/51 are misuse because they're about unrelated types of assumptions.
• 3/51 have multiple wicks or bullet points, and they fit into the following categories:
  • One page has an above-the-line wick that seems to be referring to audience reactions, one that's definitely describing an audience reaction, and one ZCE.
  • One page has a "see also" wick in the description, six audience reactions in the example list, and one I'm not sure about.
  • One page has a bullet point that's unclear because it's doesn't mention a mistaken guess, and the other I'm unsure about because it's about people getting the album's name wrong based on something other than the lyrics.

Wick check here.

• Award-Bait Song: The same with "Santa Claus Adventure" (1997, also known by its lyric "Gotta Go See Santa Claus") by Liz Callaway, minus the A Wild Rapper Appears! bridge (in fact, the song was more Disneylike in feel than "Wonderful Day", helped by Callaway's status as a veteran of Disney and non/Disney animated musicals).
• Either Or Song: Sometimes a work gives itself multiple alternative titles in the title, usually giving the short title first, with the result commonly being a Short Title: Long, Elaborate Subtitle. Using this trope these days can give a similar retraux feel as In Which a Trope Is Described. Songs with unintuitive titles often include the most prominent word or phrase from the lyrics in parentheses as an alternate title for practical reasons. Above-the-line wick describing an audience reaction.
• Nuke 'em: Randy Newman's "Political Science" (incorrectly known as "Let's Drop the Big One Now") deconstructs and mocks this trope by suggesting the flimsiest, most frivolous excuses for nuking everyone and everything (except Australia).
• Music.Alt J: It's "The Gospel Of John Hurt", not "Coming Out Of The Woodwork" or "Chest Burst Like John Hurt".
• Music.Aurora: It's not "Give Me Some Love", it's "I Went Too Far".
• Music.Billy Joel: All of these are audience reactions involving mistaken guesses.
  • It's "River of Dreams" not "In The Middle Of The Night".
  • Similarly, it's "Summer, Highland Falls" not "Sadness or Euphoria".
  • "Goodnight Saigon" is not called "We Will All Go Down Together".
  • Several of his songs have subtitles by which they're more commonly known. "You're Only Human (Second Wind)" and "Miami 2017 (Seen the Lights Go Down on Broadway)" are the most famous.
• Music.Bon Iver: A lot, due to Non Appearing Titles. Tempered somewhat by the fact that this only applies if you can understand what he's saying in the refrain anyway. All of these are audience reactions involving mistaken guesses.
  • Somewhere, somebody thinks that "Holocene" is called "I Was Not Magnificent," or something along those lines.
  • It's called "Skinny Love," not "My My My."
  • It's called "The Wolves," not "What Might Have Been Lost."
  • It's pretty easy to assume that "Minnesota, WI" is actually called "Never Gonna Break."
• Music.Bonnie Tyler: All of these are audience reactions involving mistaken guesses.
  • The song that goes "turn around... {lyrics lyrics}, turn around... {lyrics lyrics}, turn around, bright eyes... {lyrics lyrics}, turn around..." and on and on like this is called "Total Eclipse of the Heart". (Not "I Need You More Than Ever" or "Forever's Gonna Start Tonight", either) Though this is at least guessable, being the punch line of the refrain.
  • Her other big hit is not called "I Need a Hero". It's called "Holding Out for a Hero".
• Music.Buckethead: Played to an unreal extreme, sometimes it's best to assume the song don't even have a title. For example, a song by the name of "Blue Marble Moon" technically is not its official name because it doesn't have one.
• Music.Crowded House: The song is "Don't Dream It's Over." Not "Hey Now, Hey Now."
• Music.Delain: On your first listen to "The Glory and the Scum," you'd be forgiven for thinking it was called "Monster."
• Music.Derek And The Dominos: It's called "Bell Bottom Blues," not "I Don't Wanna Fade Away."
• Music.Divinyls: "Boys In Town" (not "I Must Have Been Desperate"); "Hey Little Boy" (not "I'm Talking to You").
• Music.Drake:
  • "Karaoke" isn't called "If You Gotta Go".
  • "Dreams Money Can Buy" isn't called "Don't Fuck With Me".
  • "Make Me Proud" isn't called "I'm So Proud Of You".
  • "Headlines" is not called "They Know".
• Music.Fatboy Slim: Several of his songs have popular incorrect titles taken from their most prominent samples; "The Rockafeller Skank" is routinely mislabeled as "Funk Soul Brother", "Ya Mama" as "Push the Tempo", "Star 69" as "What the Fuck", etc.
• Music.Freedom Of Choice: Their biggest hit is just "Whip It," not "Whip It Good" in spite of the trope name.
• Music.James Brown: Bad to the Bone: "I Got You (I Feel Good)" (not titled just "I Feel Good") has been used in many movie scenes with happy people. It is also a Standard Snippet in comedy trailers.
• Music.Jesus Christ Superstar:
  • The opening song that Judas sings is "Heaven on Their Minds," not "Listen Jesus" or any variation thereupon.
  • Jesus' Heroic BSoD Song is simply "Gethsemane," not "I Only Want To Say," though it is sometimes called "Gethsemane (I Only Want To Say)."
  • The finale is simply "Superstar," not "Jesus Christ Superstar."
• Music.Meghan Trainor: "No Excuses" is not called "Someone Else", even though those words show up way more in the song than the title does.
• Music.Primal Scream: The big hit from Give Out But Don't Give Up is called "Rocks", not "Getcha Rocks Off".
• Music.Radiohead:
  • "Just" is sometimes appended with "(You Do It to Yourself)" for this reason. The title appears in the song 3 times. The refrain appears 15 times.
  • The same also applies to "Street Spirit (Fade Out)."
  • "Creep" often appears on filesharing sites as "So Fucking Special" after its best known lyric.
  • Both "Myxomatosis" and "Cuttooth" have been mislabeled as "Tongue Tied."
  • "Packt Like Sardines in a Crushd Tin Box" is probably out there on hundreds of filesharing websites mislabeled as "Reasonable Man."
• Music.Randy Newman: Nuke 'em: "Political Science", sometimes incorrectly known by its refrain of "Let's drop the big one now."
• Music.The 1975: "Sex" is NOT called 'She's Got a Boyfriend Anyway', nor is "Chocolate" called "We're Never Gonna Quit It' or 'Guns Hidden Under Our Petticoats'.
• Music.The Band: It's called "The Weight", not "Take a Load Off, Fanny".
• Music.The Killers: "All These Things That I've Done" is frequently known as "I Got Soul", and has even been covered using this title.
• Music.The Mighty Mighty Bosstones: Cameo: Jimmy Kimmel ocasionally sings/plays with them live. Usually he gets to sing the Impression That I Get (also incorrectly known as "Knock on Wood") or play the oboe with them.
• Music.The Ramones: "Blitzkrieg Bop" is not "Hey Ho Let's Go".'
• Technology Marches On.Computers The soul classic "Wonderful World" (often misnamed as "Don't Know Much About History") mentions slide rules as another thing the singer don't know much about.
• Theatre.Rent: "Seasons of Love" is not called "525,600 Minutes".
• TitleDrop.Music: John Mayer's "Say" includes the word "say" 75 times. That being said, 72 of the times it's in the chorus of the song (which is different from the name of the song): "Say what you need to say". The song is also referred to as "Say (What You Need to Say)", so in this case the title is dropped "only" 36 times.
• Trivia.City Of Angels: "Angel"^note commonly called "In the Arms of an Angel" by Sarah McLachlan
• Webcomic.Iji: Additionally, one of the major morals of Iji, in addition to War Is Hell, was inevitability and the inability of one person to change the ways of a group of people no matter how hard they tried. It might not be best suited to taking on the ethos of a series containing a song best known (if mistakenly) as "Row Row Fight The Power".
• YMMV.Iron Maiden: They don't have a song called "Take Me Home" either. That song is by Iron Savior. And that's not even what the song is called either, it's called "Deadly Sleep".
• YMMV.Lords Of Acid: Believe it or not, even some of the band's biggest fans still accidentally refer to "I Sit on Acid" as "Sit on My Face". This is actually listed on a YMMV page under Refrain from Assuming, indicating that at least some tropers think it's already YMMV.
• YMMV.Pretenders: "My City Was Gone" is sometimes called "The Ohio Song" for its reference to the state in the chorus. (If the song were named "Ohio" it would be a Title-Only Chorus.) This is actually listed on a YMMV page under Refrain from Assuming, indicating that at least some tropers think it's already YMMV.

• Recap.The Simpsons S 12 E 2 A Tale Of Two Springfields: Arson, Murder, and Jaywalking: The angry, defiant Who songs Homer lists include "Won't Get Fooled Again," "My Generation" (which fit the description) and "(Mama's Got A) Squeeze Box" (which the bandmembers admitted is a joke song, "squeeze box" being a slang term for breasts). This mistake was made by a character instead of the audience (though the analysis of the lyrics is unnecessary).

• Muse Abuse: Phil Collins was possibly rightly pilloried by Spitting Image for his tendency to write this sort of stuff every time a marriage broke up. The parody song "I'm So Lonely" is a skewering send-up of Collins' angst-ridden marriage breakup single "Against All Odds". Not sure on this one, but I'm assuming it's mistaken guess.
• Ocular Gushers: Absolutely (Story of a Girl) by Nine Days, "This is the story of a girl/who cried a river and drowned the whole world." Not sure on this one, but I'm assuming it's mistaken guess.
• Rash Equilibrium: It has happened that a couple each had their on-line lovers, made arrangements to meet, and discovered that their on-line lovers were their own spouses. Unlike Escape (The Pina Colada Song), this has invariably led to hostile divorces. Not sure on this one, but I'm assuming it's a mistaken guess.
• Spelling Song: "Did I Mention" from Descendants.
  My love for you is ridiculous, ridiculous
  My love is R-I-D-I-C-U-L-O-U-S, R-I-D-I-C-U-L-O-U-S
  It's ridiculous, just ridiculous Not sure on this one, but I'm assuming it's a mistaken guess.
• The Power of Language: In the Missing Persons' "Words" ("What Are Words For?"), the singer expresses frustration at her words' apparent lack of power. Not sure on this one, but I'm assuming it's a mistaken guess.
• Creator.Gilbert And Sullivan: As was common at the time, effectively every song is named after its first line, not its refrain. The only exceptions are the ones where the refrain doubles as the first line (such as "I Am The Very Model Of A Modern Major General"). Doesn't mention anything about mistakes.
• Music.Achtung Baby: Like many examples of this trope, "Ultraviolet (Light My Way)" stuffs its refrain into parentheses. "Ultraviolet" is only heard in a background vocal near the end. Not sure on this one, since it doesn't say whether the lyrics in question lead to mistaken guesses.
• ReadyJetGo.Tropes Q To Z: The song sung at the end of "Date Night" is actually called "Date Night" according to the episode credits, but fans always call it "Real Bortronian Deal" because of that phrase being repeated in the song. This sounds more like a Fan Nickname than a mistaken guess, since it says fans intentionally use an incorrect title.
• TriumphantExample.P To R: C+C Music Factory, Gonna Make You Sweat. ~thecnoNSMB This is an entry for Most Triumphant Example, which is for tropers' own opinions.

• Music.Body Count Album: Yes, it's an album made by Ice-T and his homies, but it isn't a HipHop record. Covers a mistaken guess involving the genre instead of the title.
• Music.Lana Del Rey: References are also scattered throughout Chemtrails Over the Country Club and Blue Banisters. "Tulsa Jesus Freak" being the most prominent example with the title named after one of the major cities and referencing the Arkansas River (which is not pronounced the same way as the state). About an unrelated type of mistake.
• Music.Uh Huh Her: "The Slow Drug" is not about drugs. Harvey uses it as a metaphor for love: Not about the title. Might fit under Common Knowledge or a subtrope thereof.

• Album Title Drop:
  • Sometimes, albums aren't named for one of the songs on them — they're named for one of the lyrics within these songs. So, when you're listening, you think "Oh, that's where the title comes from!". If it's the refrain or chorus, it can make Refrain from Assuming worse, because something has that title, it's just not the song. Above-the-line wick that seems to be referring to an audience reaction.
  • Jane's Addiction's "Ted, Just Admit It.." from Nothing's Shocking: "Camera got them images, camera got them all, nothing's shocking". In fact, since the phrase "Ted, just admit it" never comes up in the song, but "nothing's shocking" does occur several times, this also leads to Refrain from Assuming. Describes an audience reaction.
  • Talk Talk - In the song "April 5th", the phrase The Colour of Spring is both this and a borderline case of Refrain from Assuming. ZCE.'
• Misattributed Song:
  • See also Refrain from Assuming and Covered Up. All Animation Is Disney for a similar trope in a different medium (and both are subtropes of Small Reference Pools). Crosswick in the description.
  • There's a song that's often called "Drink and Fight" which tends to provoke arguments in the comments about just who made it anyway every time it's posted on YouTube with a different name and attribution. (For the record, it's "Irish Drinking Song" by ska punk band Buck-O-Nine.) Describes an audience reaction.
  • Ibold Train's "A Song About You", The Arena Drive's "The Fall", and Self's "Paint By Numbers" (often also labeled "Ex-Girlfriend") are other examples of songs that have gotten misattributed to Weezer. In at least the former two cases, this isn't helped by how obscure the real artists are. Funnily enough, the Ibold Train song is also sometimes misattributed to Ozma, a band whose songs have also been misattributed to Weezer (and it's also not by Elliott Smith). Describes an audience reaction.
  • If one believes his Twitter Rivers Cuomo was at his kid's piano recital when they called “Say It Ain’t So” a blink-182 song. Though whether this is a case of Misattributed Song or Refrain from Assuming is debatable, as they very well could have been referring to "All the Small Things" which actually is by blink-182 and whose chorus opens with the phrase. Not sure on this one.
  • "Think About The Way" (not "Music is the Vibe") is not technically by Alexia, it's by Ice MC with Alexia as an uncredited guest vocalist. And Cascada didn't cover it, that was Groove Coverage feat. Rameez. Describes an audience reaction.
  • "Youtopia" (not "Lighter than Air") is not by Owl City, but by Armin Van Buuren featuring OC's Adam Young on vocals. Describes an audience reaction.
  • "Saturnz Barz" (not "All My Life") is not by Popcaan. It's a Gorillaz song featuring vocals by Popcaan. Describes an audience reaction.
  • "Suedehead" (not "I'm So Sorry") is not by The Smiths. It's Morrissey's solo debut single. Describes an audience reaction.
• Music.The B52s:
  • The song "Dry County" doesn't use those words until near the end of the song. The refrain (or the closest there is to one) goes "Just sit on the porch and swing... Sit on the porch..." Doesn't mention any wrong titles.
  • A Non-musical example with the band's first album, which is self-titled, is often mistaken as being called High Fidelity due to this phrase appearing in the upper-lefthand corner of the cover. This was actually placed there to mimic labels on older album sleeves. Not sure about this one since it's unrelated to lyrics.
