Dynamic Flash MP3 Player

[Xtreme3]

I am in the process of building a dynamic site, using php and MySQL DB, which will feature music bands. I want to have the option for people to listen to their music. I want to put a flash mp3 player in (don't know if I should purchase one or build one from scratch and suggestions) to play the music. So here is the problem: how do I get one flash file to pull a specific xml file, for the music titles and songs, based on a URL id. Or if anyone know of another way to do this I would love to hear.
Thanks

don't know if I should purchase one or build one from scratch and suggestionsI be happy to build one for you with all your needs should you decide to do that.

As for:
how do I get one flash file to pull a specific xml file, for the music titles and songs, based on a URL id. Without hearing much more details, I'd recommend using FlashVars.
