this is the best MP3 player I've seen. Although it need a little code edit, because out of the box it doesn't work in IE (at least it didn't work for me).
I than changed file /plugins/content/mp3browser.php on line 217.
At param value I replaced "$musicDir . DS . $file" with "$musicDir . '/' . $file".
Before that it somehow made wrong file path. Instead of / it put empty space which affected IE preformance.
Beside that it's the best MP3 playlist plugin out there! Thank you!
