That covers rap, industrial, punk, blues, Japanese anime music(pop, blues, jazz) and metal. On another note, GSC takes place in Chi-town and KMFDM, Sister Machine Gun, and TKK were all members of legendary electro label Wax Trax! which was based out of Chicago. Also cool to get some car songs on there since the lovely Rally Vincent and dangerous Bean Bandit love their cars.

Here's a link to a previous list of comic book soundtracks including Seven Soldiers, 52 and some some various DC mega events. I'll post some other ones later.
