Oh hands down, that's the best song from Rhapsody. It's actually been a VGM favorite of mine... probably since around the time Disgaea came out in the U.S., which is when I went back to see Marjoly's roots. Yeah, it's a VGM great.
My favorite composers are Junichi Nakatsuru, Hideyuki Fukusawa and Chamy ISHI. Sorry I can't be cool and say my favorites are more obscure composers, I like what I like
