I may have just found the soundtrack for the next retro-gaming party. Someone has put together a few “arcade ambiance” recordings together. Here are the folks involved in the project. I can see this being more relaxing to me than playing an ocean surf or babbling brook recording.

What initiated this is that the virtual arcade for the Xbox 360 opened its doors. The folks at Kataku took a tour. Listening to the video the editor made, you can hear the same arcade ambiance. Also from the video, looks like the initial collection is a bit of a disappointment. Shows promise, though.
