While going through the fan voting thread I listened to every song at least once, going through most a few times. This shortlist represents all the entries which I consider contenders for the top 5 spots. The items are mostly in order of a metric which is some combination of my preference, the song's connection to the art, and how good the piece actually is.

The Shortlist:

1. Aim 2021 - Spring Petals ahhh,,,, shit.

2. AIM - Tranquility such a hard decision if this should take the top spot or not
