MPD is pretty popular too http://www.musicpd.org/ It has a client/server model and you can create your own music streaming service by controlling it remotely and streaming back over http. ncmpc/ncmpcpp is a client for mpd that resembles cmus quite a lot.

mpd with ncmpc has brought my music very close to me - just a couple of keystrokes away.

Regarding Winamp, I've always loved it's tagline "Winamp kicks the llama's ass" (or was it butt?).
