This is an old thread but I also use DeaDBeeF and I'm very fond of it. What I like most about it is its flawless gapless playback. I use to have a hard time finding a good gapless audio player for linux a few years ago. I never liked rhythmbox, I was using amarok which wasn't up to doing a proper gapless playback (back then, now I don't know), then switched to mpd (which works great, but the deamon setup can be a bit bothersome, especially using lots of external HDDs). Then DeaDBeeF came along. It's very lightweight and straightforward, and does a marvelous job.
The first thing I do after installing a new distro is to install DeaDBeeF.
