Every Saturday you'll find a new track of music to enjoy of the videogame related variety. What you'll find hear is music that might not necessarily be music directly from a videogame, but be inspired by it at the very least.
Thinking back to the launch days of the Xbox 360 one of its most important features for me was its custom soundtrack capabilities. Project Gotham 3 was easily my favorite 360 launch game and so was all of the music I listened to while tearing up the Xbox Live leaderboards. Assuming time machines are possible sometime in the future I'd definitely go back in time to add Danny Byrd's Throw Ya Hands to the playlist I used to listen to while playing PGR3.
