I hate:
Junk Food (except the occasional chocolate)
Rap (it doesn't make sense, there's no bridge, no middle 8, it's all the same)
Crazy Frog (enough said)
Sitting Around All Day (I have to do something!)
Inactivity (I hate coming to a forum with no new topics)
MTV (destroyed music)
Hypocrites
Ego-trippers (if thats a word)
There's more...
