Thanks for these thoughts. My design for the sleeves includes information oriented to DJs. A friend suggests I may be better off sending jewel cases, though - harder to get lost. I just hate wasting that much plastic (plus it costs more). Thoughts?

Folkiedave, the tracks are mostly between 3 and 5 minutes, mostly between 3.5 and 4.5. Only one is longer than 5, and it's still not that much longer.
