I don't understand what you mean by "what kind of MP3". I'm going to guess you mean "What kind of MP3 player do you have". At the moment I don't have any mobile devices, and I'm working on saving for a good one so I can store all my music and actually use it without having my laptop around. In my library, I have 8 and a half hours worth of music, and it's taking up 587.5GB on my HDD. Since I come across music I like a lot, I add new music a lot, but I get bored of old songs a lot, and delete them. It practically balances itself out, but in the long run I end up accumulating music.
