There wasn't really much effort involved. Pick a few discs off the CD rack that I thought will clash interestingly, load up the cd tray of the cheap all-in-one turntable/tape deck/radio/cd unit I had in my room, hit the 'shuffle' button until it tells me it's gonna shuffle everything together, hit play.
Looking Fantomas up on Wikipedia makes it sound like they'd go pretty well with "twenty tracks that sound like the choruses of twenty different songs" and "ninety-something 1s blank tracks plus a few industrial songs", though.
