So, any opensource music cms exist?

[Sykat]

I want to create a music download database. With bellow function.
A cool admin panel.
getid3 system inside.
Album arrangement.
category or tag system.
ptetty file management.
Discription field on an album.
Searching system
It will be great if there are a system with user registeration and they can create different playlist by adding songs from site just like imdb.
Design doesn't matter. I am professional web designer.
If no opensource then name professional paid script.
