B.E.R.

"The Night Begins to Shine" is a song by the band B.E.R. popularized by the Teen Titans Go! TV series. The song was originally co-written in 2005 and produced between 2013 and 2014 as an "'80s-style song" for a music library. The song was first featured in the Teen Titans Go! episode "Slumber Party" as a throwaway joke and it became popular with fans of the show. The song was subsequently featured in the episode "40%, 40%, 20%", and was prominently featured in two specials, the four-part 2017 special "The Day the Night Stopped Beginning to Shine and Became Dark Even Though It Was the Day" and a five-part sequel released in 2020, "The Night Begins to Shine 2".

The special also featured two other songs by B.E.R., "Forever Mine" and "Rise Up", as well as three covers of the song from Fall Out Boy, CeeLo Green, and Puffy AmiYumi. A spin-off series from Teen Titans Go! by Cartoon Network was announced in 2021, but as of 2026 no production updates on the project were announced.
