Question: What English songwriter once featured in the album "Whitney: The Greatest Hits"?

Georgios Kyriacos Panayiotou (25 June 1963 – 25 December 2016), known professionally as George Michael, was an English singer, songwriter, record producer, and philanthropist who rose to fame as a member of the music duo Wham!  He was best known for his work in the 1980s and 1990s, including hit singles such as "Wake Me Up Before You Go-Go" and "Last Christmas", and albums such as "Faith" (1987) and "Listen Without Prejudice Vol.  1" (1990). <SEP> Greatest Hits is the first greatest hits album by American singer and songwriter Mariah Carey, released in the United States on December 4, 2001 by Columbia Records.  It is a greatest hits double album: CD 1 is primarily a collection of Carey's hits from 1990 to 1995, while CD 2 is primarily a collection of hits from 1996 to 2000.  In 2011, the album was re-issued outside the US with the same track listing, under the title of "The Essential Mariah Carey".  In 2012, "The Essential Mariah Carey" was released in North America with a slightly different track listing, replacing some hits with their extended club mixes, and others being completely removed in favor of tracks that had not been released as singles.  Much of the artwork inside the album booklet is very similar to that of the "Greatest Hits" release. <SEP> Whitney: The Greatest Hits is a compilation album by American singer Whitney Houston, released in May 2000.  The collection includes four new songs—"Could I Have This Kiss Forever", duet with Enrique Iglesias, "If I Told You That", duet with George Michael, "Same Script, Different Cast", duet with Deborah Cox and "Fine"—all of which were released as singles.  The set consists of disc one with ballads and disc two with uptempo numbers and remixes.  Houston's performance of "The Star-Spangled Banner" at Super Bowl XXV, and 1988 Olympics tribute "One Moment in Time" are also included in the set.  It also includes three other songs that had never appeared on a Houston album: "One Moment in Time", "The Star Spangled Banner", and "If You Say My Eyes Are Beautiful", a duet with Jermaine Jackson from his 1986 "Precious Moments" album.  Along with the album, an accompanying VHS and DVD was released featuring the music videos to Houston's greatest hits, as well as several hard-to-find live performances including her 1983 debut on "The Merv Griffin Show", and interviews. <SEP> Dance Again... the Hits is the first greatest hits album of American singer Jennifer Lopez.  It was released on July 20, 2012, by Epic Records, to coincide with the launch of her first world tour, the Dance Again World Tour.  Lopez previously conceived plans for a greatest hits album in 2009, but instead opted to use the material recorded for her seventh studio album, "Love? ", which was released by Island Records in May 2011 after her departure from Epic Records in 2010.  As Lopez owed the label one last album to fulfill her contract, she began work on a new greatest hits album in November 2011.  She later became unsure whether she wanted to go along with plans to release a greatest hits album or a new studio album, eventually deciding on the former.
