Agreeing with the above poster, Xenogears has possibly the best soundtrack on the PS1 (yes better than any FF or Chrono), and in my opinion is the best RPG ever made. Finding copies is difficult but very worth it, translation is rough, but the extent of the game and its messages are fantastic. It nearly wasn't released in the US because of the religious imagery and criticism it contained. Oh, and this mix is awesome.
