From the view of how many Katamari music there is on it along with some by "The Seatbelts" and "Yoko Kanno" (btw both great band and singer :) selections of awesomeness) it is a very interesting mix of sorts. A few I have to admit never heard of. I just have to say that for the most part of the downfall is the song from Puffy AY. Don't get me wrong, they're quite the Jpop couple (I'm sorry to have heard that they were demoted to 'gaishin'[foreigner] in their social life). It's just I was never really a fan of the TT show. Other than that, I think I would love it.
