CLI Audio players
There are many other CLI audio players for Linux. MPlayer, for example, can play audio files from the command line. Music Player Daemon has many front ends but can also be used from the command line. Other notable apps that don't need a GUI are mpg123 and mpg321, mjs, jinamp, benmp3, xcplay, mcplay, and ncxmms. Choose the one that serves you best, and play that music loud!
Its a short, concise view into a few CLI players for linux. If your looking for some then there are a few decent links to some that are on offer to you. Personally I prefer MPlayer, but thats mainly due to the fact it plays more than just music. ;-P
