I just want to point people towards this page:
http://curious-cat.net/rays/
It's a database of awesome Ray series-related information, including, above all, "Pianistic Ray", a collection of eight piano re-arrangements of some of the series' best music tracks.

The only thing I'd like is to find a way to rip the tracks and throw them in my ipod. It seems you need to have QuickTime Pro to do that.
