if you want to add your own song to your profile, the best way to do it is to create another profile then convert it to a band one.lets call it random123. then upload your songs!
log out of random123 and back into your proper one, and view random123. there should be a rectangle with the songs on it, with options to play etc. you want add to profile.

And there you go

oh and i have a myspace too, here
