As alacrion says on their Soundcloud page:
“I should note: the only editing I did to this was aligning the tracks. I didn’t isolate the vocals and put them over the same backing track; Glee were already using the exact same track, which is, as far as I can tell, JoCo’s recording.”
In response to the controversy, Coulton rereleased “Baby Got Back” as a single with the name “Baby Got Back (In the Style of Glee)” on iTunes, Google Play, and Amazon. All proceeds will be going to the VH1 Save the Music Foundation, and the It Gets Better Project.
