Well, the synth tunes on 'Anything Could Happen...' and very ¿hypnotic?
Anyway, that seems to be what they class themselves as anyway along with Metal/Screamo which is more appropriate for them with all the Drop C guitar riffs and screaming. (not like AHHHH, like shouty scream, like Slipknot...but I hate Slipknot)
You know their stuff better than I do, nsa, so I won't argue! As for Slipknot, I don't own any of their CDs (not sure I ever will), but at least those guys knew how to put on a show for their fans. (Someone asked me a while ago what I thought of them, and I have to say I'd sooner have attended a Slipknot gig about five years ago than have to sit through the over-earnest tedium of bands like Keane or Coldplay...)
As for the rap (musical genre)/hip hop (style/way of life) debate, it depends what you listen to. I like a lot of the old skool but don't have much truck with all the hos and bling of gangsta - give me Public Enemy any day over Ma$e. But if you don't listen to it, you ain't never gonna like it...
