U2 is known mostly for giving everyone their album Songs of Innocence for free, but this cover is actually pretty good.

One of the first things I saw today is another fun cover song from Leo of Frog Leap Studios. It's always a good day when he posts one of his amazing metal covers of a pop song. He takes those silly pop things and turns them into something people would actually want to listen to!
There have been a lot of Metallica covers over the years, from big name bands to unknowns, to cello covers, to lullaby versions for babies. Now there are some creative people out there creating new versions like this one. A medieval instrument version of "One" from ...And Justice For All.
