whats is the code to put music in for myspace,thanks

You go to the artist's myspace (use the search feature) and click add

Or do you mean something more complex than the myspace player?

there's a cool website that has different types of mp3 players at : http://www.myflashfetish.com and you can load music at http://www.fileden.com for free

Or do you mean this?
