We'd like to think the greatest cinematic moments happen when a music scene induces some serious audience toe-tapping and head-bobbing. Then head-bobbing gets you chair-bouncing. And chair-bouncing just turns into all-out dancing like a fool. All while singing along as if you've missed your true calling in life, of course.

Check out our list of the happiest music movie moments that we turn to over and over again.

7. Singin' in the Rain: "Singin' in the Rain"
Gene Kelly, who famously had a 103-degree fever during this classic dance number, makes us smile no matter the weather ... and it's a glorious feeling.

15. Hairspray: "Good Morning Baltimore"
This 2007 musical is based on the 2002 Broadway adaption which is based on the 1988 John Waters' film (phew!) and opens with Tracy Turnblad (Nikki Blonsky) waking up in a delightful mood to the sound of her alarm clock. She takes us on a musical journey, all the while cheerily singing good morning to her city.
