well for a lot of things. but if you're using it with a discman, i'm sorry but writing cds and playing them is the only thing you can make with it. but if it's a net md like mine, you use it to trabsfer music, edit music etc. actually it's not much of a use, and it sucks if you ask me. you can upload to md, but you can't upload to pc from md. it's one great feature is that the tracks are so tiny
what do you use it with?
