Valve MP3 Player
The player can be activated using the
mp3 console command. It is able to access music files of installed Source games as well as those stored on an external file system (e.g. on a hard disk or CD).
Currently, it sports a built-in volume control with a (non-functional) Mute button, Shuffle mode, reading of ID3 tags as well as a (currently not implemented) seeking bar.
