Side Tracks is a compilation album by Steve Earle.
 The album was released in 2002.
"What Have You Done for Me Lately" is a song by American singer Janet Jackson from her third studio album "Control" (1986).
 Jackson co-wrote the song with its producers Jimmy Jam and Terry Lewis.
 It was released on January 13, 1986 as the album's lead single, by A&M Records.
 After two unsuccessful albums and a management change, the singer began developing a new album.
 "What Have You Done for Me Lately" was originally penned for one of Jam and Lewis's own records, but the lyrics were rewritten to convey Jackson's feelings about her recent divorce from James DeBarge in January 1985.
 It revolves around a woman's frustration with her partner in a relationship.
Unbreakable is the eleventh studio album by American recording artist Janet Jackson.
 It was released on October 2, 2015, and is the first album released under her independent label Rhythm Nation, disseminated by BMG Rights Management through a partnership with the singer.
 Jackson had parted ways with Island Records in 2008 due to dissatisfaction over the company's lack of promotion for her tenth studio album, "Discipline" (2008).
 The singer began recording new material with producer Rodney Jerkins the following year, but eventually abandoned the project.
 She became busy with film roles and embarked on a worldwide concert tour, and in 2013 announced her third marriage to Qatari businessman Wissam Al Mana.
 Two years later in May 2015 Jackson announced that she would embark on the Unbreakable World Tour and release "Unbreakable".

June Christy (born Shirley Luster; November 20, 1925 – June 21, 1990) was an American singer, known for her work in the cool jazz genre and for her silky smooth vocals.
 Her success as a singer began with The Stan Kenton Orchestra.
 She pursued a solo career from 1954 and is best known for her debut album "Something Cool".
 After her death, she was hailed as "one of the finest and most neglected singers of her time."
E=MC² is the eleventh studio album by American singer and songwriter Mariah Carey.
 It was released in the United States on April 15, 2008 by Island Records.
 The singer began recording the album in 2007 in Anguilla, after writing and composing most of its material during and after her 2006 Adventures of Mimi Tour.
 Carey worked with several notable songwriters and producers during the course of the project, including Jermaine Dupri, Bryan-Michael Cox, Stargate, The-Dream, Tricky Stewart, Scott Storch and Danja.
Lazy Afternoon is a studio album recorded by American singer Barbra Streisand.
 It was released on October 1, 1975 by Columbia Records.
 After releasing the "Funny Lady" soundtrack earlier in 1975, the singer began working with new musicians for the project following the mediocre critical response generated from her previous studio album, "ButterFly" (1974).
 Recorded in April 1975 in Los Angeles, "Lazy Afternoon" contains pop standards.
 Producer Rupert Holmes wrote four songs on the album, and Streisand received her first songwriting credit for the song "By the Way".
 She also included a few cover songs, such as Four Tops' "Shake Me, Wake Me (When It's Over)", Stevie Wonder's "You and I", and Libby Holman's "Moanin' Low".
Peter Kingsbery is an American singer songwriter who cofounded the band Cock Robin in the 1980s.
 He grew up in Austin (Texas) where he studied classical music.
 He moved to Nashville (Tennessee) where he began his career as a musician (he accompanied Brenda Lee on piano on a few tours) and then to Los Angeles at the end of the '70s where he began a career as a singer/songwriter.
 He composed a few songs for Smokey Robinson, and one of his compositions, "Pilot Error", sung by Stephanie Mills, got some success in the dance charts in 1983.
 At the beginning of the '80s, he founded the group Cock Robin with Anna LaCazio, Clive Wright and Lou Molino III which enjoyed great success in Western Europe mainly.
 Failing to break their native country with a first self-titled album in 1985, the quartet became a duo of Kingsbery and LaCazio when they released their second album in 1987.
 After the band split up in the early 1990s after a third album, Peter Kingsbery enjoyed a fairly successful solo career, releasing four albums over a decade, and scoring a major hit in France with the song "Only the Very Best."
 With his fourth album he tried his luck singing in French, the language of his adopted country (living there since some years back).
Seohyun (born Seo Joo-hyun) is a South Korean singer, member of Girls' Generation and its subgroup Girls' Generation-TTS.
