Well first off, I enjoy this song, but whatever, personal tastes.
Secondly, and more importantly, this song wasn't in Jet Set Radio, it was in the sequel.
I've been playing Risen, thanks to the most recent humble bundle. The game is a lot of fun, but rather difficult. You have to be careful with enemies. No rushing. Even the little monsters can hurt a lot. The plot can get stupid at times. Often it's "Do work for me and I'll give you gold" with an overall tone of "GOLD RULES!!!" The main character is witty and fun though.
