Jajuk is a free, cross-platform music player available for Linux, Windows and Mac OS X, written in Java. I never used Jajuk before, so I tested it for the first time today, an I'm really impressed. Let me explain.
Jajuk 1.9 RC2 running in Kubuntu 10.10 Maverick Meerkat
The version I'm going to talk about is 1.9 RC2, which is the version currently included in Ubuntu 10.10 Beta. Jajuk is written in Java and it uses the mplayer engine for playing audio files, and comes with a full set of features, most of them reviewed here.

I must say, the interface of Jajuk is really cool and will probably fit any person who likes to have the widgets and layouts organized in a different way from the default. Why is that? Well, first of all Jajuk offers tabs (which actually look like some kind of sub-windows) for each different item, like: different tab for playlist, cover, lyrics etc. These sub-windows can be moved around, minimized/restored, and even organized in tabs. This is very powerful and very useful in my opinion. Take a look at these screenshots, which show Jajuk's GUI organized in various modes:
