Well, judging from how much our musical tastes differ, I guess I should completly avoid this then.
I found XIII fantastic, and also XIII-2, if you removed these horrible trance tracks first (and Crazy Chocobo from disc 4). In fact, I would consider disc 4 (again, remove that horrid Chocobo track!!) one of my few loop-ad-infinitum discs. It has this incredibly beautiful vocal theme song by KOKIA, where she really shines IMO (which is not always the case with her "contract" works, but I guess they left her a good amount of freedom here). And then the moment at the end of 'Eternal Paradox', where the theme's melody slowly enters... just magical. That part always gives me shivers.
And yeah, I know, neither Noel's Theme nor 'Eternal Paradox' were done by Hamauzu
