Argh. I thought the way this work is you got soundtracks for all the games. Anyway, it's worth it just to play the game and hear the damn music. I linked the full soundtrack, though not in the best format.
Absolutely, the soundtrack alone is worth the playthrough. Here's a link to the studio's soundcloud which has the soundtrack up at what I think is a better quality than youtube is offering.
