I don't think anything will ever top Bastion for me personally. First time I bought a video game OST and still listen to it regularly.

I can give some leeway to Hades 1 lacking somewhat because he went ahead and voiced two major characters he wasn't supposed to on top of the music and the amount of voiced dialogue per character in that game puts most AAA titles to shame. None of its bad, its just less "I'm buying the album for this song immediately" like the prior games.

I also personally like how dumb the Scylla song is simply because its meant to be that dumb, but I see your point on it.
