How do you find music for an MP3 player???
Well good girl, you can either obtain it illegally, downloading it from sites such as limewire (a lot of people recommend them here); or you can purchase it legally from sites such as itunes; or you can 'rip' your own cds onto your computer, which just means converting your cds to mp3 files; or you can trade mp3s with your friends.
Limewire is a good site, so is frostwire or you can use ITUNES
Limewire if free and you can download anything
