The Interview has found yet another way to piss someone off. K-Pop star Yoon Mi-Rae is suing Sony for using her song in the film without her permission. Her agency, Feel Ghood Music, had been in contact with Sony to license a song fortuitously named "Pay Day." A deal was never finalized, however, and once The Interview was realized the agency realized Sony went ahead and used the song anyway.
Here's the offending clip:
With a lawsuit now in the picture it looks like Sony could lose even more money on The Interview.
