"Better When I'm Dancin'" is a song recorded by American singer-songwriter Meghan Trainor for the soundtrack to the film The Peanuts Movie, based on the popular comic strip of the same name created by cartoonist Charles M. Schulz. Trainor co-wrote it with Thaddeus Dixon and co-produced it with her brother, Justin. Epic Records released it on October 14, 2015, as the first and only promotional single from the soundtrack. Backed by an instrumentation of salsa-inspired drums, the tropical song has house influences and optimistic lyrics that were inspired by Trainor's fans.
