The phenomenon that is Frozen hit theaters on Nov. 27, 2013. Since then, there's only been one song coursing through all of our minds: "Let It Go."

This thing is a beast. "Let It Go" could just not be stopped this year. It was the first Disney song since 1995 to make it into the Billboard Hot 100, helping the Frozen soundtrack shoot to No.1, too. It picked up an Academy Award for Best Original Song. And of course, it inspired countless covers and parodies on YouTube. Everyone from a children's choir to Minecraft to fathers and daughters uploaded their own renditions of the ballad.

While Frozen was great and all of this is lovely, it has also helped make "Let It Go" such an earworm that you just cannot get it out of your head no matter how hard you try. It doesn't help that you can't turn on the TV, radio or log onto the Internet without hearing the song. Even in your real life, you probably know some people who never miss an opportunity to sing this tune, whether they're young or old. Jennifer Lee, one of the directors of Frozen, is sorry about that.

"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,'" Lee recently told The Hollywood Reporter for the magazine's 2014 Women in Entertainment issue. "I've gone from, 'Thank you,' to, 'Sorry!'"

See? Even she knows how annoying the songs from Frozen can get after hearing them for the 12,000th time.

Beyond Frozen's massive success, Lee has a personal attachment to the film and its songs. Her 11-year-old daughter Agatha Lee Monn actually sings as the pre-teen Anna in the middle verse of "Do You Want to Build a Snowman?"

With the short Frozen Fever set to debut before Disney's new live-action Cinderella movie in theaters March 13, 2015 and a Frozen sequel rumored to be in the works, the animated feature is sure to bring us even more songs to annoy us, I mean, entertain us, for years to come.
