Good Cover, Bad Cover

I was tagged or memed or whatever to pick a good cover song and a bad cover song. I couldn't make up my mind on the good cover so there are two. There are tons of bad covers but the one I picked was the first to come to mind.

Good Cover
Alien Ant Farm's version of "Smooth Criminal" by Michael Jackson


Atreyu's version of "You Give Love A Bad Name" by Bon Jovi


Bad Cover
Jessica Simpson's version of "These Boots..." by Nanci Sinatra
