"575" is a song recorded by Japanese recording girl group Perfume for their third studio album, JPN (2011). It was written, composed, arranged, and produced by Japanese musician and Capsule member Yasutaka Nakata. The song was included as a B-side track for the group's single, "Voice". It was also released exclusively to Uta stores in Japan on July 14, 2010. Musically, "575" was described as a mellow Japanese pop song. It marks the first time that the group perform in a rap structure, delivered after the first chorus. The song's title, and the structure of its verses, derives from the structure of haiku, a Japanese style of poetry which comprises a 5-syllable line, a 7-syllable line, and then another 5-syllable line.
