Wow. Good one! I have quite a few! How about that gawdawful "Blue" for starters? Anything, and I mean *anything* by Cher, but most especially that heavily synthesized recent travesty of hers. N'Sync? My daughter calls them InStink (I gotta agree). Is it any wonder I do not listen to much if any radio? And the list goes on, but I'll spare you all that. :D
