As I began reading this thread, I thought... oh my God... what is everybody going to list? I'm pretty impressed by the variety and diversity shown by people on the list. I probably shouldn't be, since we're all avid music fans, so it's not all that much of a surprise that people enjoy a wide range of music. Anyhow, since I have no shame and don't fear the onslaught of comments, I'll list a few of the groups in the genres I listen to:

AC/DC
Tchaikovsky
Go-Go's
Manowar
Billy Joel
Nena (Any German's out there? Is she still around?)
Starship
Tokens
Steppenwolf
Technotronic
Creedence
No Doubt
Bryan Adams
4 Seasons
Shirelles
Vanessa Mae
Little Richard
Wham
Poison
Kenny G
and tons and tons and tons of soundtracks...

I've got a few MP3's from the Backstreet Boys, Britney Spears, and Michael Jackson, too... and I don't care who has a problem with that! The beats are pretty good. If it doesn't sound great I don't OWN it! But, I'll listen to something that's got a decent beat to it. I just won't spend $18 on a CD for one song. (Not to bring that subject up again...)
