Someday I Will Be Fine... I ALREADY love this OST! The incredible contrast of the very beginning of the composition and its continuation in the form of... PERCUSSION!
Submerged In - Sounds like something alien... The main motif is well reminiscent of underwater levels from old games.... And the second part is epic)
Fight The Doubts Away - Oh.... I LOVE THIS BASS AAAAAAH!!!1!
She Used To Play This - Sounds like the perfect musical accompaniment to pictures with happy memories of the past...
Today Is The Day - So... This is by far my favorite song in your soundtrack. Slaps! The increasing dynamics, a little madness and a short sweet piano solo at the very end of the track - all this creates a cool atmosphere of battle!
And One Day I Did - Heh... It sounds cute)
In general, you have a very diverse soundtrack with an atmosphere perfectly suited to the jam theme. I liked it! Thanks!
