For workout music I like heavy as fuck , usually a mix of technical Death Metal and simplistic but brutal stuff. The occasional Melodic-ish band makes it in there like Impious, as long as the aggression is there I am pretty happy.
Actually Impious is a band I got back into due to going for runs, Hellucinate is a killer fucking album. The rest I could do without. Speaking of which, now I must play it.
Now playing - Impious - Suicide Park
Killer song.
