Need A XML Music Player Type Deal. Like Used On Myspace.com

I will be using a PHPWebsite script for my site. I need someone that can incorporate a MXL or some type of audio player like used at [login to view URL] To play multiple songs. I need someone that can incorporate it into the PHPWebsite so that the admin could upload music files from the admin area to the actual music player just like at [login to view URL] where the user can upload their own music for visitors to view and listen to from their profile page. If this cant be done from PHPWebsite admin then I will need someone that can build me a player & some type of back door access so that I would only have to login & up load or delete music tracks all from online.
