Hi, Deni, anyone can sign up for an mp3.com page and upload files. You need to create an mp3 file that fits their specs, and is in the public domain, or for which you own the copyright, or have rights to use it. The "premium" feature is a new charge of $19.99 a month US, starting the first of next month, that will allow you to be payed back for a minimum number of unique listener plays each day. If you just want to put up mp3 files, you don't have to pay anything.
