La Bamba by Rancid.
Hurt by Johnny Cash
Fear of the Dark by Cradle of Filth
Boyz in the hood by Dynamite Hack
Those are all i can think of. One by Children of Bodom, the metallica song. I like when it crosses styles, i.e. Tori Amos singing slayer (terrible version, but you get the idea).
THE WORST-- Sweet child of mine by sheryl crow
