I'm with Bill Bailey on The Edge. Far too reliant on effects, albeit some talent.
Satriani and Vai - not musically genius. I have far too many of their albums, and most of it is technical b****** with, imho, very little originality/compositional/asthetic consideration. Especially of late, it's all throwaway.
I'm not really understanding why Brian Transeau aka BT is also popular or regarded as somewhat of a genius either, also could someone explain Trent Reznor to me? The most genius thing he has done as far as I can see is made himself a millionairre off Ghosts, the worst NIN record ever. Beyond that, it's all really simple industrial with pessimistic lyrics - genius, really? I suspect Phil Collins is more of a musical genius really, and I'd rather listen to How To Destroy Angels.
