"Brooklyn Nights" is an unreleased song by Lady Gaga. It was considered to be released on her fourth studio album, ARTPOP (2013). She revealed the song title on September 20, 2013 via Twitter, but the song did not make the final track list. The song was competing with "Mary Jane Holland" for track number twelve on ARTPOP. "Mary Jane Holland" won because Gaga "wanted to spend more time" working on "Brooklyn Nights". During a Twitter Q&A on October 13, Gaga confirmed that the song would be available instead through the ARTPOP application. However, plans for the app were shelved and the song remained unreleased.
