PHP MP3 playlist

/ Published in: PHP
Save to your folder(s)
I found this script out in space and think it's rad. Click on the URL to see this authors profile. The easiest way to use this script is to place it in the same directory as your mp3's then make a request to the php. The php will return an XML with the song Path, Title, and Author which is great for Flash.
