I recently installed Amarok. After a few days, I am convinced it is the BEST music player for Linux. It is not only a great player, but it has extensive organization functions.
Here to download:
AMAROK
Be sure to read the wiki.
They just integrated the libgpod library from the GTKPOD project, so you can stay in one app and fire playlists to your iPod.
If you run Linux and have a pile of music to get organized and you have an iPod, get this installed.
If you like to rip and burn CD mixes, get this installed.
