I think I posted this on reddit once before but stopped using that website/don't remember my login due to using 10 Minute Mail, sorry.
This was a Space Dandy remix or fan song posted to Bandcamp around the time it premiered. It had a pink album cover. It was that bubblegum pop lo-fi music before that was really a popular genre. The beginning of the song started out with the English dub of QT saying, "Dandy! Hey Dandy!".
It's also worth mentioning that it was released as a "Name your Price" so I downloaded it for free. I had it on my old laptop but that computer is dead and I never held onto the charging chord.
It was also probably posted onto Youtube by the artist but I can't find it there either. A while back I combed through Bandcamp's search bar using the phrase Space Dandy but never found it.
