There are covers, and there are COVERS! Some bands can pull it off and others, not so much. Some covers make you think: 'Man, I think that's better than the original'. Case in point: Shinedown with Simple Man. Ok ok ok, I know you're probably throwing your mouse at your computer in disgust, and that's fine. Skynard made the track and made it well. Shinedown though, yeah, they killed it.
