I have quite a few. But there are some songs I have that sound like the MIGHT be covers, but it's the only version I know of. I know of a few examples, though.
Come on Eline(???) by Save Ferris, origonally done by ???.
Tutti Fruiti by Queen, origonally done by ???.
Rock and Roll Music by The Beach Boys, origonally done by ???.
What's your favorite style of music?
