Yeah, it is fun to pull out an old one that you haven't heard for a long time. I just recently listened to one of my first comps which was an African Mix and it sounded pretty cool. Probably been well over a year since I'd listened to it last. But I do tend to only listen to the recent ones, and usually only near the time I make them. Usually by the time I finish one, I'm starting to get sick of it so it's good to give them some extended time off. Never tried the random play thing, though. Would almost seem a crime after spending all that time fretting over the sequencing. Guess spontaneity has its benefits too
