Word(s) that only ever appeared in one (hit) song, ever.

'Recipe(s)' is in Joni Mitchell's "Raised On Robbery" (which only went to #65 US anyway)

This word will most certainly be popping up on the charts via Katy Perry sometime soon, but 'Prism' in "Joanne" by Michael Nesmith (#21 US in 1970)

Ha, I sort of knew all those were going to be duds when I posted them. All part of the fun I guess.

"injustice" in "Easy To Be Hard." "Social injustice," no less...

"social injustice" appears in Janet Jackson's Rhythm Nation.

"trigonometry" from Sam Cooke's "Wonderful World".

Also puts in a forgettable appearance on will.i.am's ''T.H.E. (The Hardest Ever)'' but that peaked at #36 and I'm not convinced anybody in the world remembers it, so ''hit'' is probably a stretch.

was that the one with (yeesh) Jagger on it?

if so, not a hit. forgotten dud already.

Hahhaa, yes, that one.

I think "Ancoats" only appears in "Matchstalk Men etc"

Has there ever been a hit single version of 'This Old Man'? If not, I'm going to nominate Pop Muzik by M as the only hit to include 'knick knack paddy whack'

Is Ultravox's Vienna the only hit song to include the word 'pizzicato'?

sometimes I have an idle reverie about being hired to write the lyrics for the X-Factor winner's song, and writing a lyric composed entirely of words from this thread

or comprised, even

wtf you took seven minutes to decide to replace the right word with the wrong one

"Knick knack paddy whack" is also in Ludacris's "Get Back."

'Club Country' by the Associates has 'refrigeration' and 'soldered', both of which feel like they might be contenders?

Squonk - Steely Dan, "Any Major Dude (Will Tell You)"

Long shot, but "devious" on "Sex and Candy"?

"Fake plastic submarine" - from a long-forgotten rock radio hit from 2000, "Right Now" by SR-71

Pant(s) that only appeared in one (hit) video, ever.

I find it delightful that "parthenogenesis" appears 3 (now 4!) times on this thread

Saw Tori Amos upthread: Sneeze?

"membrane," "mainframe," and "Sumo" in "Insane in the Brain"
"wonderland" in "Your Body Is A Wonderland"
"The Bronx" and "Oprah" in "Jenny From The Block" (can't be true, surely?)
"redecorated" and "field trip" on "Who Dat"
"Pez," "Fun Dip," and "macaroni and cheese" in "Summer Girls." Excepting "Cherry Coke" on principle vs. "chicka-cherry cola."

Well, there's 'Wonderland' by XTC for a kick-off..

Hrm! Wiki doesn't show that one charting anywhere...

at one point I wanted to compile a list of unusual words mentioned in Pet Shop Boys songs. potential candidates here include "jasmine" (as in the plant) and "Issey Miyake"

Ok "Jasmine" is in Summer Breeze The Islets..

The Isleys. My spelling corrector!

boogie wonderland ffs

think winter wonderland might've been a hit

exalted, in the new clean bandit

oh duhhhhh re: both of those wonderlands. That'll teach me to cruise my Spotify pop junk playlist tipsy at 2 AM.

"membrane," "mainframe," and "Sumo" in "Insane in the Brain"

"Membrane" appears in Grandmaster Flash's "The Message" and LL Cool J's Rock the Bells.
"Sumo" appears in Big Pun's "I'm Not a Player".

Don't think there are any other hits with "Mainframe" though.

"strongly" on Silverchair's "Tomorrow"?

Candidates from "Simply Irresistible": 'inscrutable,' 'irreversible,' 'irrefutable.' 'Permissible' and 'mythical' maybe less likely.

Prodigy - Breathe

"Psychosomatic"

The Avalanches' Frontier Psychiatrist has psychosomatic in it, though it is obviously a sample from somewhere.

Was gonna say "not a hit but the first thing I thought of too" - but was pleased to just discover it hit #18 in the UK. Way to go, Avalanches!

And the sample, it turns out, is from a comedy routine entitled... "Frontier Psychiatrist." http://grooveshark.com/#!/s/Frontier+Psychiatrist/2gfJCf?src=5

OK, how about "Hydromatic"

(You know the song)

On "This Beat Goes On/Switchin' To Glide": "zoomy," maybe "mobilize" and "hoot."

Ha -- definitely way to go, Avalanches. Now about that second album...

Okay, I feel good about this one - "amoebas" in John Hiatt's "Thing Called Love." A #11 on US Rock for Bonnie Raitt.

Amoeba wasn't in "Kokomo"?

hahaha, would go well with the "mounds of rotten steak" reportedly found in Martinique (thanks, ILX)

"Bravado" in "Baby Come Back" by Player?

"Worcestershire sauce" in "Crack a Bottle." Kind of a wretched song but it would be cool if the "bottle" in question actually contained a tangy condiment for beef dishes.

"Cargo," in "Rock the Boat"?

Well, there's also this, but I doubt it was ever a hit...
