I say it's Satanic sounding because it's much darker sound(evil), raw, and loose. The melodies (especially not my funeral one in the second preview) are the type that don't give that cheerful feeling like FTR did, they're more of a damn it sounds evil but I'm gonna bang my head to it also.
SKO in the clearer samples makes that part of the song sound acceptable. And speaking of atmopshere, that's the only song that gives the the FTR atmosphere. As Joonas would put it, I can see the trees.
The rest of the songs definitely have a type of 'evil' vibe, completely different than previous albums. Satanic, at least for me, doesn't have to be some hardcore super evil sounding music, example being Reinkaos album.
