I do actually enjoy some of Tool's music (particularly the stuff on enima) but I get really sick of their "we are just such f**king geniuse" attitude.
Coming out behind a f**king sheet at a concert and demanding no one take pictures of you just screams "I am a wanker" to me, and for that reason I simply refuse to watch them live (I have had several opportunities as well).
Tool and U2, despite being clearly polar opposites in terms of music, have both managed to have the same effect on me.... great music, shame about the band members and die hard fans being absolute twats.
Personally I find Matt Bellamy to be a superior musician to all of them.
Blink are no doubt a very simple, straight forward band. But then again so were ACDC, Metallicca, the Stones, the Beetles and countless other legendary groups (not that I am putting blink at the same level of some of those groups)
Sometimes creating simple music that is still original is a great talent in itself.
