Valve is planning to integrate music playback and library functionality in Steam, and will soon give some users access to a beta test.
Detailed in the Steam Music Beta community group, the service will be available in Big Picture and SteamOS interfaces. Valve added that desktop features will follow “soon”.
Steam Music allows users to listen to their song collections while playing games by opening up access to their local music directory. In addition to the music files, the service will support album and artist views.
