Exclusive: Hear Scarlett Johansson's Catchy Pop Song From Sing

Don't think that this month's animated film Sing is going to just be for kids; the movie, which stars the voices of Scarlett Johansson, Matthew McConaughey, Reese Witherspoon, and more, is full of covers of your favorite pop songs. But there is one musical centerpiece of the movie that's an original song, and it delightfully comes from Johansson. As teen porcupine Ash, Johansson belts Ash's original song, "Set It Free," and we have the first clip of her singing, just as she's discovered by theater owner McConaughey (yes, as a koala). Get excited for the full song when the movie comes out on Dec. 21.

You can also pre-order and get the song now.
