A youtuber by the name of Doukas Pj.
Doukas Pj was a youtuber who created his channel on March 19th, 2010 and started making videos early of 2015. He made content in 2019-2021 which I started watching then. Doukas unfortunately deleted his channel in March of 2021, and made a new channel named DoukiePetunier422, which he doesn't make the same content he used to make. he used to make content based off of My Singing Monsters, and specifically a fan-made universe called Upbeats, Upbeats were created by MantisBoi / MantisGirl, and Doukas Pj made a fanmade 6th element of the Upbeat class called Aura. These were the Aura Islands, fan-made songs based off of Upbeats, he made about 16 of them, and updated a few of them. His content was extremely niche, and rarely anyone reuploaded or even archived any of his music. I've been trying to look for specifically his islands Thrillic Theatre, Mystical Tundra, Aura Hotlands, Vortex Cyberspace, Planetary Orbit, Error Egypt, and basically almost all of them. I really hope someone has an archive of him anywhere, because I would really appreciate it
