Day 8 ~ Best sound track
One of the Need for Speed games (Sorry, I can’t tell you which one -_- ) has a pretty fantastic soundtrack.
And the Final Fantasy games always have some pretty interesting tunes on them too. At the very least, those songs are fun to play on the piano 😀
Other than those, I usually turn off the background music on most of my games. I’d rather listen to my stuff while playing a game as it’s more relaxing.
