Orange Box
Guitar Hero II & III

I've been playing a lot of Beautiful Katamari this weekend, and it doesn't spin down / stop the disc noisily with that one.

Perhaps it has something to do with the way the game data is formatted on those games and the way the 360 reads them.
Same here. Some games it does it, some it doesn't. I've noticed on a few of the games it only does it at certain points. Like one game when I quit to dash is the only time it makes the noise while another at the very beginning of the intro it does it once and never again.
