All great imitation, even when it's parody, respects the original source. The covers that disappoint fail to do this.
Notably missing from Crossfade's list are the pain-inducing covers that have been discussed to death. Examples: Celine Dion's cover of AC/DC's "You Shook Me All Night Long" (need I say more?); anything Limp Bizkit ever covered (George Michael's "Faith," The Who's "Behind Blue Eyes," Pink Floyd's "Wish You Were Here"); Britney Spears's cover of The Rolling Stones' "Satisfaction."
Here's what's left: Some unturned stones of awful, some familiar ones that haven't had nearly enough negative attention, and some that will leave you retching. The only antidote? Check out the originals.
