As you might already know, Valve generously released soundtracks for their games completely free of charge. However they don't let you download them without downloading the whole game, which is not ideal.

It works this way because soundtracks are considered just another piece of downloadable content. But fear not, it is possible to force Steam to download a specific depot.

Here's how you can download Portal 2 soundtrack:

Open Steam console: steam://open/console Enter download_depot 620 323180 (620 is Portal 2's appid, and 323180 is soundtrack's appid) Wait for it to download.

There will be a message when the download is complete, with a path where you can find downloaded content, something like \Steam\steamapps\content\app_620\depot_323180 .

If you go to Portal 2's depot page you will find Portal 2 Soundtrack (323180) Depot there, and you can see its size of 463.75 MB, and that's how big the depot folder should be when it's done.

This process can be repeated for any depot/soundtrack on Steam, as long as you have a license for them.

For your convenience, here are commands for other soundtracks:

Half-Life Soundtrack: download_depot 70 323130

Half-Life 2 Soundtrack: download_depot 220 323140

Half-Life 2: Episode One Soundtrack: download_depot 380 323150

Half-Life 2: Episode Two Soundtrack: download_depot 420 323160

Portal Soundtrack: download_depot 400 323170

Portal 2 Soundtrack: download_depot 620 323180

Free to Play Soundtrack: download_depot 245550 323120

We hope you find this simple tutorial useful, and we might do more of these in future.
