I'm pretty sure any music you hear other than live-played music that isn't with an acoustic instrument is, by that definition, "compooter music." After all, everything you hear that isn't accoustic/live has to go through some type of amplification (which does require computing) not to mention basic reverb and delay effects most amps produce. If not that, you're probably hearing it through some type of electronics which once again would make whatever you're hearing qualify as "compooter music."
Would you mind expanding upon which three topics you're talking about specifically? The ones that you said were nothing but dubstep.
