I'm among the people that feels the series hasn't spawned a particularly great soundtrack since Dracula X (including the remake). SotN was merely "okay" by my books, but it didn't come close to matching anything before it, the rockers on the OST included. The lone possible exception is Circle of the Moon, but to be fair, one of the things I loved about it was the remakes. The other GBA and DS soundtracks, I've certainly listened to and hoped for the best. I didn't seem to find much (nothing immediately comes to mind, anyway). Oh, and I found Lament of Innocence completely abysmal. The other PS2 one was slightly better, but didn't warrant shelf or HD space (maybe if I felt the game might have been worth playing, it would have garnered nostalgia points, but alas...)
So I've more or less learned not to pay new CV soundtracks much attention. Oddly enough, the past year or so, I've probably paid CV4's OST more attention than I ever have previously. It's brilliant.
And it must be said...Yamane has been on my shitlist since she took the realms of Suikoden III and (albeit, with some help) ruined the reputation of that entire series' music.
