NEW YORK, Dec. 11 (UPI) -- Singer-songwriter EJAE says she joined KPop Demon Hunters back in 2020 when it was a small creative team trying to put together an animated musical movie that would eventually become a global phenomenon.

Her first creation with co-director and co-writer Chris Appelhans, co-writer Danya Jimenez and music producer Ian Eisendrath was "How It's Done."

"It was a lot of pressure, but I was writing a lot of girl crush songs back then, so it was really fun to experiment with my voice. It had to be iconic -- girls slaying it and killing it," EJAE said at a special screening of the film this week. "That's how it started, I think."

EJAE would ultimately provide the singing voice for heroine Rumi, as well as several songs for the Netflix sensation, which was recently nominated for three Golden Globes and five Grammys, including Song of the Year for "Golden."

The film follows a trio of pop stars who perform under the name HUNTR/X and fight evil in their downtime.
