It sounded really nice but... where was it in the game (if anything, that was a compliment. you were so good you masked what it originally sounded like :D).
The only thing I could think of was the typewriter theme (although that's the only song that I ever really listened to).

I love that typewriter theme. Though I believe it's called Save Room or something. It's so relaxing. But about this song. I used to have the OST for this game on my old PC but not anymore so I can't check it and I don't even remember how the song went but it was about 3 minutes and had violins and piano and now I'm not even sure that this sounds anything like it so maybe this was completely random tune after all.
