"Time After Time" is a song by American singer-songwriter Cyndi Lauper.
 It was recorded by Lauper for her debut studio album, "She's So Unusual" (1983), with Rob Hyman (co-writer and founding member of the rock band The Hooters) contributing backing vocals.
 The track was produced by Rick Chertoff and released as a single on January 27, 1984.
 It was the second single to be released from the album and became Lauper's first #1 hit in the U.S.
 The song was written in the album's final stages, after "Girls Just Wanna Have Fun", "She Bop" and "All Through the Night" had been written.
 The writing began with the title, which Lauper had seen in "TV Guide" magazine, referring to the 1979 science fiction film "Time After Time".

Apothecary Rx is the second studio album by Carl Hancock Rux, produced by Rob Hyman (of "The Hooters") and Stewart Lerman.
 The album also features singer Stephanie McKay and contributions from jazz violinist Leroy Jenkins and singer-songwriter Marc Anthony Thompson (of "Chocolate Genius").
 The album was selected by French writer Phillippe Robert for his 2008 publication "Great Black Music": an exhaustive tribute of 110 albums including 1954's Lady Sings The Blues by Billie Holiday, the work of Jazz artists Oliver Nelson, Max Roach, John Coltrane; rhythm and blues artists Otis Redding, Ike & Tina Turner, Curtis Mayfield, George Clinton; as well as individual impressions of Fela Kuti, Jimi Hendrix, and Mos Def.
Good Bread Alley is the third studio album of Carl Hancock Rux.
 Titled after a close-knit historically African American district of shotgun houses that once occupied a segregated neighborhood in Miami, Florida, the cd was released by Thirsty Ear Music, produced by Carl Hancock Rux with songwriting and co-songwriting credits from Geoff Barrow, Vinicius Cantuária, David Holmes, Rob Hyman, Stewart Lerman, Darren Morris, Phil Mossman, Vernon Reid, Tim Saul, Jaco Van Schalkwyk, and Bill Withers.
 The cd tackles religion, sexual politics, war and media overload, in the tradition of Marvin Gaye and Donny Hathaway, employing supersaturated, open-ended soul music with bluesy vamps, touches of minimalism, and slide-guitar licks providing a rich backdrop for Rux's sardonic baritone, achieving a pop-gospel synthesis.
"Private Emotion" is a pop song written by Eric Bazilian and Rob Hyman and originally recorded by The Hooters, for their 1993 album, "Out of Body".
 The song was picked up by Ricky Martin and included on his "Ricky Martin" album.

 As Turkey was one of the countries where Martin's popularity was at its peak, Ricky Martin sings the song with Sertab Erener instead of Meja in the Turkish edition of the album.
 Live performances of the song have featured other artists such as Coco Lee and Delta Goodrem.
