Indie game musician here. I absolutely LOVE the soundtrack in the game, some brilliant sounds and composition going on. I only have an issue with the music you are greeted with.
It’s a hint too intense and the vocals are annoying. I mean, they sound epic and emotional, from the perspective of the craft, wonderful stuff, real quality.
But… I’m annoyed by them, especially the repetition of the male vocalist. I don’t understand what they’re shouting, but it sounds like “fjor! ult!” and repeating it makes it stand out to me that you just repeat a sample there, which sounds a bit lazy. 
And the wonderfully emotional female vocals… I get a bit cringe feelings from those.
Overall, I’d tone the intensity down a little for the greeting music. It’s an amazing track for a trailer, but if you hear it every time you log in, I find it a bit exhausting. Might also be a bit too loud for first time players who are being blasted without having reached the settings screen to adjust their audio levels.
Other than that, the musician(s) here have my utmost respect for an amazing OST. I appreciate a lot of the details in the instrumentation and mix. The music really enhances my time in the game.
