Depends how big your harddrive is, and how much free space it's got. If it's getting above 80-90%, it's time to start thinking of other ways to store your data. If you don't listen to your music that often, you can store them on DVDs or cds, usually as mp3 files, and then just whack it in the drive when you want to listen to it. So go buy 3 dvds or a 20 pack of cds and away you go. If your music isn't compressed, you can try that - 192 kbps mp3 is plenty good enough for most uses.
