Trials of remembering - Interesting theme, but the drums need something to gel it to everything else, like a bassline.
Those fields - Similar to the menu track.The quiet whistling bird section makes this one stand out.
The feathers - Much better balanced, with some really nice melodies.
The pure - The guitar and double bass drum pedal was unexpected! Quite heavy relative to the rest of the ost but works for a boss fight theme.
