Shame to see Muse doing dubstep. They said they were gonna do something new for this album, and even if it's new for them, dubstep's been done so much nowadays, that it's no longer interesting to me... plus it reeks of 'jumping on the bandwagon'. But it's a tiny preview, i'll reserve judgement until at least the first single!
I couldn't see Edge doing something similar though, sounds too 'rough' for u2 (and i like to think they'd be a little more trend-defying!)...
