Birthday

"Birthday" is a song recorded by American singer Selena Gomez for her solo debut studio album Stars Dance (2013). It was written and produced by Mike Del Rio, with additional writing by Crista Russo and Jacob Kasher Hindlin. Matt Beckley also provided additional vocal production for the song. Musically, "Birthday" combines deep electronic dance beats and police sirens with elements of trap music. The song's instrumentation is created by blending purring, synthesized bass, snappy beats, handclaps, "oxygen-sucking" sub-bass, and trap snares with sexual moans and elements of hip hop music. Sparse drum beats and vocal chants are woven throughout the song's composition, which has been described by critics as club-ready electropunk, with trap and dubstep elements. The song was originally announced as a single, but was never officially released from the album. Thematically, "Birthday" is a party song which discusses topics such as sex appeal, self-entitlement, and girl power, while its risqué lyrics speak of a night of hard partying. The song has received comparisons to the music of several artists, including Dev, M.I.A., and Icona Pop. Upon release, "Birthday" received favorable reviews from music critics, who praised the song's unique sound and production. Upon the release of Stars Dance, the song charted at number 12 on the US Bubbling Under Hot 100 Singles. "Birthday" has charted at number 191 on the South Korea Gaon International Chart due to high digital downloads. An accompanying music video for the song was released on July 22, 2013, to coincide with Gomez's 21st birthday, and features the artist and her friends partying and singing the song in different locations, including an underground nightclub and a dark room. Background and recording "Birthday" was written by Crista Russo, with additional writing by Mike Del Rio and Jacob Kasher Hindlin, under his stage name "J. Kash". Production of the song was handled by Del Rio and Matt Beckley, who provided the song's vocal production.
