The Lego Batman Movie has an amazing soundtrack. Make sure to listen to the films main single, it sums up the character from the film extremely well. “Who’s The (Bat)Man” is written and performed by Patrick Stump of the band Fall Out Boy. The song has a way of staying in your brain long after listening to it. “I’m 100% not Bruce Wayne!”
The other title track from the movie is “Friends Are Family,” with Jeff Lewis and Will Arnett. This is a more typical/expected pop song from the film, and it feels like it could fit right in with The Lego Movie.
