This is a Flash multi-MP3 player I built a number of years ago.  Tracks are added to the playlist through an XML file. Take a look at the file sounds.xml to see how to configure your playlist.  Essentially you just add track title, artist name, and MP3 path to the appropriate XML nodes and you're set to go.

Configure only one flashvar to tell the player which XML file to use like this...

flashvar="soundFile=(path to XML file)"

Known Issues

There are a few things that should be fixed to make this player really polished.  You'll see what I mean if you play with it for a bit.

1. Artist name vanishes after clicking to the next track.
2. Moving through tracks in any sequence but 1,2,3...last seems to cause problems.
3. Reaching endpoints (first or last track) could be handled better. For example, when clicking past the final track, the player should go back to the first track - IMHO.

Well anyway, it's free so crack open the ActionScript and have some fun making it work better.  Let me know if you have any success.
