i know it's not paula or chip generated, but i liked the in game "musak" from diggers CD32.
really nice "Audio Wallpaper" background noise that kinda captured a bit of a echoy underground feeling. all wooshy synths, and then deep into the track, the contrasting pure sound of an electronic squarewave bluring out into reverb, burning out like a guitar riff falling into the sun....
sorry, imagination got the better of me there...
