Greatest Hits is a compilation album by Sonia, released in 2007. It was Sonia's first release since her fourth studio album Love Train - The Philly Album in 1998. This compilation includes songs from her second studio album Sonia (1991) and third studio album Better the Devil You Know (1993). No songs from Sonia's first studio album, Everybody Knows (which was released on a different record label), are included. Prior to the Greatest Hits release, Sonia also recorded the Motown-influenced songs "Dancing In the Driver's Seat" and "Your Heart Or Mine", both written by Barry Upton and Gordon Pogoda, but ultimately the record label chose to include no new songs for the album, so these recordings remain unreleased.
