I screw around with stuff I've done using music loops in Mixcraft. A step down from actually recording music, it relaxes me, and gives me good mixing experience with different genres I wouldn't otherwise have to interact with. I'm not a recording engineer, but I play in a band, and we record our stuff mostly on our own, so it's good to at least know the basics when mixing times come up.
Hell, I'm actually doing this right now.
