The 2011 double-disc collection The Essential Mariah Carey is a retitled reissue of the 2001 set Greatest Hits, containing the same 29 tracks in the same sequence. All Mariah's big hits of the `90s are here, including several singles that never made it to the top of the charts, and while it loses momentum by the end of the second disc, this is a good and thorough retrospective of Mariah in her prime. ~ Stephen Thomas Erlewine
