Oh, I have lots, but they all pale in comparison to Avril Lavigne.
And ditto on the ridiculousness of J-Lo. The first time I saw the video for "Jenny from the Block" I thought it was supposed to be ironic; that's how bad it was. Anybody who uses the phrase "I love my public" in a song (or anywhere else, for that matter) should be shot, ESPECIALLY if the song is about how "down to earth" they are.
