Not cover versions, obviously, but ones that happen to have the same name. Which is better? Songs with very similar titles are obviously allowed.
Silver (Jesu) > Silver (Pixies)
Blind (Hercules & Love Affair) > Blind (Talking Heads)
Repetition (The Fall) > Repetition (Helmet)
Casimir Pulaski Day (Sufjan Stevens) > Kasimir S. Pulaski Day (Big Black)
Piece of Crap (The Futureheads) > Piece of Crap (Neil Young)*
and I can't honestly decide which is better "Wake Up" by Arcade Fire or "Wake Up!" by Les Savy Fav.
*the writing credit suggests it's a cover but the words & music are so different that I'm not sure how that happened.
