Is there a good music library program
 

I like XMMS, but the only thing missing is a music library, to organize your collection.
There was one plugin a tried out for it, but I found it wasn't very good...

Does anyone know if there is anyone one being worked on, or another app (lightwight) with this ability? I don't want think I want something as big as rythymbox...

Juk is the best around AFAIK, but you could try the hayes playlist plugin if you use noatun.

What about digital DJ from the makers of Grip? Check http://freshmeat.net for more info. Although I know it's not amazingly lightweight on the backend, the front end should seem 'light'. You can also look at something browser based like netjuke, which I've personally never tried but always been very interested in...

Cool
