Mp3, xml, php and mysql

If someone could point me in the right direction for some resources on the net so I can learn how to do this:

I need to have an mp3 player (I have built one already) on my members profile pages, it needs to be loaded with the mp3 files that the member uploads, and, if they upload a new mp3, the playlist should update also so the player will play the latest uploaded trax for that member.

now I know how to use mp3 player and xml, just don’t know how to automate it with php and mysql. So if someone could point me in the right direction for an online resource for this I would appreciate it, I can’t find the right info through google.
