Britney Spears "I Love Rock and Roll" is another. Her dumb ass was quoted as saying she covered it because she really loves Pat Benatar. Think about it.
There's some awful version of "A Whiter Shade of Pale" that's been on Lowes' muzak system for about a year now every time I go in. It sounds like Celine but it isn't. I don't know who it is, but that one is just vomitocious. It's probably somewhere on here.
