the reason the glitches seem so natural is because the sound is used to create its own beat, and the sound that is part of the glitch is used in a different way to make another beat. the glitch noises create a base for the song, like a bass, and the rest of the sound is used for creating a catchy and good sounding tune. and, unlike most songs, the glitches create a sense of originality. they stop parts of the song being the exact same as others and makes every sound we hear feel new and vibrant.
overall, this song has to be one of the best i've heard. i forgot about the game for 1-2 years and came back to it, but throughout that time period i never forgot the song. the glitches seem to create a sense of great musicality. 10/10.
