One of the main reasons this track is my favorite is because of the synthwave at the beginning, it perfectly compliments chiptune because of how much depth it gives to the song, along with the euphoric feeling. Another is how the occasional "beep" and "boop" that plays just reverbs out in a very special way, matching with the beat, it compliment to the music even more.
This also made me think: what if you combined synthwave and chiptune in one song?
