From just my iTunes, filtering out the local bands that fit
“She” The Monkees and The Hoodoo Gurus
“Louie Louie” The Kingsman (et al) and The Pretenders
“Stumble” R.E.M. and Collapsis
“Run Run Run” Velvet Underground and Concrete Blonde
“Rock and Roll” Velvet Underground and Led Zepplin
“Ride” The Vines and Liz Phair
“Money” The Beatles and Pink Floyd
“Little Sister” Elvis Presley (and Dwight Yoakum, at least) and Concrete Blonde
“Lies” The Rolling Stones and The Knickerbockers
“Jane” Barenaked Ladies and Ben Folds Five
“Help Me” Joni Mitchell, Oingo Boingo and Concrete Blonde (three different songs)
“Do It Again” Brian Wilson/Beach Boys and Matthew Sweet
“Beautiful” Carole King and The Go-Go’s
There are way too many to list, but my uneducated guess for the song title with the most number of different, easily-identifiable (still played on radio), versions would be Fire
Jimi Hendrix Experience
Crazy World of Arthur Brown
U2
Bruce Springsteen & E Street Band
Deaf School
Prodigy
…And a lot more less popular
Huh. Well, at least I coined a spiffy new term for the phenomenon. Pop song homonym: Use it, love it, spread it.
Further fodder for discussion: From this thread and the last one, it’s obviously not uncommon to see two or three different songs with the same title. What’s the threshold for it being an interesting phenomenon? Five? Eight? Ten?
