Well, let's see here...

1) Twangy Country Music
2) Moldy Oldies my Mom busts out on 45's when she's drunk
3) Slipknot and their ilk
4) Jesus music is hard to listen to (except Cartman's faith+1)

...You know what, I'm gonna turn on MTV right now, see what's on, let about 2 seconds pass so I can register exactly how horrible the song is, come back here, and add it too the list. Here I go...

...LMFAO!!! MTV2 has a show on right now called "Most Irritating" how ironic! That makes the rest of my post easy.

5) The Macarena
6) Blue (dabadeedabadi)
7) Barbie Girl
8) Tubthumping


Good enough list for now, I don't wanna take all the easy ones :)
