The final season of Glee premieres on Jan. 9 and there's now a promo video featuring Lea Michele belting "Let It Go," a choice that's apropos and annoying at the same time. According to this 20-second teaser, Rachel and Kurt are back at McKinley to revive the Glee Club, but Sue's gonna give them hell.

"You two just entered Thunderdome," says Sue. "You will beg for death."

Speaking of begging for death, the Frozen director Jennifer Lee recently apologized to parents for children around the world being obsessed with "Let It Go," saying, "A year ago, I'd meet people who, when they found out who I was, they'd say, 'Oh, we love the songs! We sing them all the time.' Now they're like, 'Yep, we're still listening to those songs.' I've gone from, 'Thank you,' to, 'Sorry!'"
