Forgive me if I'm mistaken on these and I don't know much about YouTube
Some songs you might not know are covers:
Aretha Franklin, Respect (Otis redding or Wilson Pickett, can't recall)
Soft cell, Tainted Love.( Don't know the artist but I think it's Motown)
Blinded by the light - this is a Bruce Springsteen song
And of course lots of Dylan songs have been covered
