I'm ashamed to say that I've never actually dived into the DQ soundtracks. A shame we missed out on the games, though! I loved playing DQIX on my DS. Back when I had DQIX, anyway. To be totally honest I've listened to more soundtracks more then I've played the games the soundtracks were written for. Lufia one among them. I expect this trend to continue as the soundtracks interest me more then the games most of the time.
If you liked FF and Chrono Trigger in the SNES era you might like to check out Front Mission: Gun Hazard. It's Uematsu and Mitsuda's only collaboration on a single score and it's fantastic from what I remember. It's where Uematsu's more "industrial" style in FFVII was born.
