I wasn't expecting anything great from the FFXIII-2 OST, I thought FFXIII's was excellent but what was released for FFXIII-2 didn't sound that great.
Those samples have completely changed my mind, especially "wish".
Hamauzu and Uematsu are my favourite composers, every Final Fantasy game I have played has had great music.
EDIT: Correction, not every sample is great, the vocal saples sound awkward and out of place.
