Have you ever desired a game for it's soundtracks?

After watching my dragon house mate play 'Beautiful Katamari' for the seXbox360, I got curious about the soundtracks. Whilst searching for them, I came across the soundtracks for one of it's prequels entitled 'We Love Katamari' and yes, I'm now looking to get this game on the basis of loving it's soundtracks! *dances*
