After repeated failed attempts at trying to make a better master of the song Mount 511, I just decided to upload the old master that I still had from 2021, when this song was first published.
It'll now be allowed for commercial uses as well, so if you want to use this in an animation or a game, feel free to do so. Also, bitrate has now been cranked up to 320 with a 20k cutoff, so unless you have Apple Music Lossless or something, this is your best option at a good quality version of this song.
