So, I really like the soundtrack to Chobits, and was wondering if the kind of jazz used in there is a specific genre, or if there was any other music out there that's similar to it (doesn't have to be anime related or japanese, but could be).

EDIT: Sorry if that was a little unclear, I actually hadn't listened to the soundtrack in a while and assumed all the songs were similar, just did and realized they weren't. Here's a few examples of what I'm talking about:
