So you hear your favorite song come on, and you're immediately stoked.
Then, suddenly, the song doesn't sound quite right.
It's a cover!
Some covers are a performer's hat tip to a song that inspired them.
Like this cover of Simon and Garfunkel's "The Boxer" by Mumford & Sons:
Fun Fact: Paul Simon accompanied Markus Mumford on this track, offered exclusively on Mumford's Babel: The Deluxe Edition.
And some covers are an artist's new interpretation of a song.

Maybe your favorite cover is done by an artist who normally sings songs from a completely different genre.
