Kesha's recording career may still be in legal limbo, but her music's still making its way out into the world.

"Butterscotch" is the latest Kesha song to surface thanks to a newly recorded version by Krystal Jung of K-pop girl group f(x) used in an ad for Korean cosmetic brand Etude House. Longtime Kesha fans know "Butterscotch" as a track that didn't make the singer's debut album Animal from 2010, but has been floating in around in multiple demo forms around the Internet. 

Krystal's new ad shows that "Butterscotch" has been reworked for the K-pop scene with English and Korean lyrics, and the fact that the song is a collaboration with Etude indicates it could be released in full song after the brand has released new tracks from its models like Kryrstal and K-pop rapper Beenzino.

So while we're not getting totally fresh Kesha music, at least we're getting something, right? Also, Krystal sounds great on "Butterscotch" and it would definitely comfortably fit on any of f(x)'s excellent albums.
