AWOL nations got a cover album a couple years ago. There is at least one Abba song on it.

Chris Cornell did a couple of covers I cant get enough of. Acoustic Nothing Compares to you.

And a cover/mashup of Metallica's Ones lyrics to U2s One Lyrics which is amazing.

I follow a guy called Leo Morachioli who does metal covers of popular songs. I really enjoy Leo's version of toss a coin to your witcher and also his cover over final countdown. His videos are rad.

Lourdes all along the watchtower is good

Alien Ant Farm did a fun cover of Smooth Criminal is good too
