Need a pick-me-up? This music video featuring the cast of Pitch Perfect 2 [1] will do the trick. It's for an original song called "Crazy Youngsters," and Ester Dean takes center stage, providing the main vocals. Brittany Snow [2] and Anna Camp also star, along with Flula Borg. The video is fun, and the tune will definitely get into your head. The song is on the Pitch Perfect 2 soundtrack (along with another original song, "Flashlight" [3]), but why wait?
