I currently use iTunes in Windows, and desperately need a similar program for Linux.

Things I like about iTunes, and want to have in a new program:
-Sorting by id3 tags
-Ease of setting id3 tags
-Folder management.

Does anyone know a program that could do these for me? I'm using mplayer and a script I wrote to manage playlists, but I guess I'm looking for something graphical. I've tried a few already, but nothing really struck me as being what I was after.

Suggestions?

I haven't tried it myself, but you could try GTKpod.

... I looked at their site - that's an open source iPod manager; I don't have one!

Any other suggestions?
