I can't stand:
1) That bananas song -- I thought it had died out but I just heard it again.
2) "Let's Get it Started" -- along with anything else by the Black Eyed Peas
ETA: Ok - Does ANYONE remember the song "Thug Life" by "Thugz Nation"? It's on their "Fresh Off Tha Mothership" album. This group came out of a small town in Georgia and I remember a time when that song was all you ever heard on Georgia radio.
Here's a link to the song's remix:
