The Katamari Damacy games pull from a wide range of musical influences, encoumpasing rock, jazz, techno, j-pop, industrial, classical, and more.  Even if one song on the soundtrack doesn’t interest you, try the next one.  It just might be the one that pulls you in.  I don’t know what style this track is in.  Just plain weird.  It’s called Katamari Nah-Nah and it’s from the original PS2 game that started the series.
