Blue

"Blue" is a song by Welsh singer Marina, at the time known professionally as Marina and the Diamonds. The song was written by Marina alone, and produced by David Kosten. Appearing on her third studio album, FROOT, it’s the 4th track on the album, and was released as the 5th single. Described by Diamandis as both '70s inspired and "the most pop-sounding" on the album, "Blue" was the first song she recorded for the album. In a 2014 interview with Line of Best Fit, Diamandis elaborated that even though "Blue" is the album's "biggest sounding song," she did not release it as the lead single because she did not want Froot to be thought of as a "huge pop campaign" with a "Top 40" route.
