The Music area is currently in a testing phase. You can upload MP3's by going to:"My Account" >> "Submit Items" >> "Upload Music"
If you have music files uploaded, the music player will automatically be visible on your profile page. If you have no music files uploaded the music player will not be visible.
The "MUSIC" link at the top of the page will bring you to a currently non-functioning page. This page is also currently under development.
Try uploading a few MP3's (Max of 10) and let us know what you think in the forums. We will keep you updated on the progress. (Video section will be coming soon!)
