The vines - overrated. I can't stand their "get free", it gives me a splitting headache.
I don't particularly like jamiroquai either...also overrated. Sometimes i listen when i hear a song in the car, but its usually the trigger for me to start flicking stations.
Otown - manufactured...and their song "liquid dreams" - i hope the pre-pubescent girls its aimed at don't understand!
Other than that, i like most types of music and although i may dislike specific songs, have very little problem with the actual artist. Even those i've mentioned, its not a blanket hate. If they came out with a good song, i'd like it. Even The Vines' cover of "ms jackson" isn't bad...
