WOW is the debut solo studio album by American singer Wendy O. Williams, released in 1984 by Passport Records.
 It is her first album appearance, to be credited to her after the success with The Plasmatics, which had gone on a hiatus during that time.
 After the release of the album, "Coup d'État" (1982) with The Plasmatics, the band opened for KISS on tour.
 By the end of the tour, The Plasmatics' recording contract with Capitol Records wasn't renewed and Gene Simmons approached Williams and Rod Swenson about producing an album.
 As to avoid legal issues with Capitol, they decided not to use The Plasmatics' name on the record in any way.
 Simmons also felt it would give more freedom to add additional musicians to the album.
 "WOW" is a hard rock album influenced by heavy metal, which marked a musical departure from Williams' previous material with The Plasmatics.
 Williams was nominated for Grammy Award for Best Female Rock Vocal Performance for the album in 1985.
A backing track is an audio recording on audiotape, CD or a digital recording medium or a MIDI recording of synthesized instruments, often of a rhythm section or other accompaniment parts that live musicians play along with or sing along to.
 Backing tracks enable singers and bands to add parts to their music which would be impractical to perform live, such as string section or choir parts which were recorded in the studio.
 A backing track can be used by a one person band (e.g., a singer/guitarist) to add bass, drums and keyboards to their live shows without the cost of hiring extra musicians.
 A small pop group or rock band (e.g., a power trio) can use backing tracks to add a string section, horn section or backing vocals to their live shows, giving a fuller, richer sound.
The Pinkees were an English power pop band from Basildon, Essex, active in the 1980s.
 The band members were Paul Egholm (vocals, guitar), Andy Price (vocals, guitar), Max Reinsch (guitar, keyboards), Nevil Kiddier (bass) and Paul Reynolds (drums).
 Piano and additional vocals, when recording, were supplied by their producer Keith Bonsoir.
 They released four singles and an album on Creole Records from 1982–1983.
 Their second single, "Danger Games", reached number 8 on the official UK charts (although it was claimed to have achieved the feat through chart hyping and suspicious sales patterns, and did not appear on some other charts at all) and gained them appearances on BBC TV programmes such as "Top of the Pops" and "Pebble Mill at One".
 The eponymously titled album was released on vinyl and cassette but it has never been issued in CD format.
 It stands at number 123 on the list of albums in the "Ultimate Power Pop Guide".
"Roc Boys (And the Winner Is)..." is the second single from Jay-Z's tenth studio album, "American Gangster".
 The song is produced by Diddy and two of his producers known as LV and Sean C from his production team, The Hitmen.
 It features additional vocals by Beyoncé, Kanye West and Cassie.
 The song samples "Make the Road by Walking" by The Menahan Street Band.
 On December 11, 2007, "Rolling Stone" named it the best song of 2007.
Clint Crisher (born January 23, 1973) is an American pop singer and songwriter.
 He is believed to be the first American R&B or pop singer to be openly gay from the beginning of his career.
Tattoo It was the title of a 1990 album by American pop / Hi-NRG singer Paul Lekakis.
 The album was released on Sire Records.
 It contains the song, "Boom Boom (Let's Go Back to My Room)", which Lekakis had previously released in 1987 on Polydor Records.
 Two of the tracks on the album, "You Blow Me Away" and "My House", were produced by Shep Pettibone.
 The track "Are You Man Enough" features additional vocals by Lisa Bellamy.
The moon-eyed people are a race of people from Cherokee tradition who are said to have lived in Appalachia until the Cherokee expelled them.
 They are mentioned in a 1797 book by Benjamin Smith Barton, who explains they are called "moon-eyed" because they saw poorly during the day.
 Later variants add additional details, claiming the people had white skin, that they created the area's pre-Columbian ruins, and that they went west after their defeat.
 Barton cited as his source a conversation with Colonel Leonard Marbury (c.1749-1796), an early settler of Georgia.
 Marbury, a Revolutionary War officer and a Congressman in the Second Provincial Congress of Georgia (1775), acted as intermediary between Native American Indians in the state of Georgia and the United States government.
"Walking on Air" is a song recorded by Australian recording artist and producer Anise K.
 The song originally features guest vocals from American rapper Snoop Dogg and American singer Bella Blue.
 In January 2014 it was re-released worldwide with additional vocals by Lance Bass and specially for Belgium featuring Lance Bass and Ian Thomas.
James Lance Bass ( ; born May 4, 1979) is an American pop singer, dancer, actor, film and television producer, and author.
 He grew up in Mississippi and rose to fame as the bass singer for the American pop boy band NSYNC.
 NSYNC's success led Bass to work in film and television.
 He starred in the 2001 film "On the Line", which his company, Bacon & Eggs, also produced.
 Bass later formed a second production company, Lance Bass Productions, as well as a now-defunct music management company, Free Lance Entertainment, a joint venture with Mercury Records.
Cecil Altman Boone (born June 1, 1935, Jacksonville, Florida), known as Nick Todd, is an American pop singer.
