I thought Final Fantasy X's soundtrack was really bad, and Dirge of Cerberus: Final Fantasy VII's soundtrack was... decent, I guess, so I was quite suspicious of Final Fantasy XIII's soundtrack. However, I think Masashi Hamauzu finally got it right with this score. There's plenty of great tracks in the soundtrack, they're quite memorable and the production values are high, considering how many songs are fully orchestral or have vocals. It's hard to compare FFXII and FFXIII's soundtracks (or even the games), since they're so different, yet I enjoyed them both. My favorite tracks on the FFXIII OST are probably Final Fantasy XIII - Miracles and Born Anew. Oh, and I actually like Kimi ga Irukara.
