"Better When I'm Dancin'" is a song recorded by American singer-songwriter Meghan Trainor for the soundtrack to the film, The Peanuts Movie. The song was co-written with Thaddeus Dixon. Released by Epic Records on October 13, 2015, as the first single from the soundtrack. The song, which is a tropical track, strays from Trainor's usual musical style, being described as "breezy and harmless" with traces of house music.
Trainor performed "Better When I'm Dancin'" on The Tonight Show Starring Jimmy Fallon on November 5, 2015. She also performed the song on Dancing With The Stars season 21 finale on November 24, 2015, followed by her collaboration with Who Is Fancy and Ariana Grande, "Boys Like You".
Directed by Philip Andelman, the video premiered on Apple Music on October 13, 2015 and debuted on Vevo the following day. It features Trainor with appearances from Snoopy, Charlie Brown, among others characters from Peanuts.
