Great work spotting the references you did! This track was originally made for part of an Adachi Rei compilation album, (Machina Mori) and all the samples you see scrolling in the bg of the DAW that make up the song are other tracks off that album as well as tracks of Jamie's discography! The whole song itself is a big celebration and like you said you can really feel it in Jamie's composition. So much joy and appreciation and good vibes π
Another fun fact: Adachi Rei is a completely artificial voice bank made of audacity samples and digital noise! Theres funding to get her a proper vocaloid voicebank right now as well, so hopefully you hear more from her in the future πΆ
