Steam News announces the Steam Music player is now out of beta, and available to all Steam users, offering an integrated way to enjoy your personal music collection while playing games on Valve's service. They celebrate the news with the release of Valve soundtracks DLC for all who own the corresponding games, and have put a bunch of their games on sale in case anyone was holding out for a free soundtrack before finally committing to a purchase. Here's word:

Now it’s easy to listen to your music collection while you play games on Steam.

Point Steam to the MP3s on your computer, then browse your collection of albums and artists. You’ll also find your Steam Soundtracks DLC in your Steam Music library when the associated base game is installed. Listen to albums, queue up mixes, and create playlists you love, right in your Steam library. Best of all, it’s all available right within the Steam Overlay, so you can control playback without leaving your game. The Steam Music library and player consist of all the basics you need to enjoy your music without switching tasks.
