Blue Orchid from White Stripes would cut well in an intro/pull shot imo. I'm a rock junkie so I always love a bit of rock. APC ftw btw, love yer work
Trance fits well with the nuke stage imo; tho I can't see any reason why you can't use both if you cut/mix it well. For example: Pull: rock song with wild intro, fade out to a boss emote (it is WoW after all and we love that geeky shit :P), then fade in with some trance for the dps phase.
