It's its own thing. There are some very memorable tracks, and many not so much. It's also got a lot more volume than most other FF soundtracks, clocking in at 12+ hours of music for A Realm Reborn and Heavensward (not to mention the tracks reused from the original release), so the goodness has a lot more room to be spread out in. Overall, it works superbly in the context of the game; it may not fit personal taste, and that's understandable, but it might grow on you a bit when you're in the heat of battle, facing the gradually escalating fight with Titan, or facing a goblin-esque mechanical labyrinth. It felt weird when I first heard it, but it works out splendidly when used in its context.
As for Soken: agreed, that's the caveat that has me puzzled and unable to fully trust this wasn't stolen. Even if he hadn't heard the song, it would be in good taste and humility to recognize that there is indeed that similarity there.
