Season 1 Episode 8 of Helluva Boss, entitled Queen Bee, featured a song titled "Cotton Candy" performed by the episode's titular character, who is voiced by American singer Kesha. However due to legal issues with her record label, the episode was delayed for over a year and the song ended up being by performed by Rochelle Diamante instead. I would assume that a version of the song performed by Kesha was recorded before they ran into legal trouble, especially since Kesha herself co-wrote it.
I believe the original recording (if it was recorded prior to the legal issues) will likely remain lost due to how record labels have a tight grasp on their artists.
yeah vivziepop will probably have it in her archive somewhere but its gonna be a while till it imergas, then again kesha may relese it soon as apart of her album in like 10 years. then again with all the hate vivziepop is getting its only a matter of time till someone tries to hack her.
I think an alternate cut of the episode with the original kesha version could exist. Maybe an extended cut on newgrounds?
Newgrounds has a pretty strict "No Copyrighted Music" rule when it comes to uploading videos, I'm guessing this extends to music that a record label doesn't want released so they can just send them a cease and desist and Newgrounds would have to comply and take the extended cut down.
