The double-disc 2011 U.K. collection The Essential Whitney Houston bears some strong similarities to the 2000 U.S. set The Greatest Hits, sharing 22 of its 35 songs. And it’s not just the big hits that overlap: there are a clutch of remixes that carry over, all bunched together on the second disc just like they are on The Greatest Hits. Consequently, The Essential Whitney Houston plays much like The Greatest Hits; even if it has a handful of songs not on the 2000 collection, it covers the same territory equally well and equally entertainingly.

The four-year wait between 2002's Just Whitney and her previous album, 1998's My Love Is Your Love, was half that between that record and its predecessor, 1990's I'm Your Baby Tonight, but it felt twice the length, since Whitney Houston's career nose-dived during those four years. She retreated from the spotlight and as she cancelled concerts, scrapped albums, and pulled out of public appearances, rumors swirled that she and husband Bobby Brown were dangerously addicted to drugs. Following a disastrous performance at the September 2001 Michael Jackson tribute concert, where she looked as if she had already wasted away, the chattering reached a fever pitch and she needed to restore her reputation – hence the title of Just Whitney, an assertion that she's returning to her basics.

A compilation released in various territories outside the U.S., including the U.K., The Ultimate Collection covers Whitney Houston's career through 1998's My Love Is Your Love, containing most of the notable singles she released throughout the '80s and '90s. It's a fairly straightforward set, though there are some alternate mixes in place of original versions (including "I'm Your Baby Tonight"), which is not noted on the outside of the packaging. Some will find fault in the number of notable exclusions, including "Miracle," "You Give Good Love," "I Believe in You and Me," and "All the Man That I Need" – all of which were Top Ten R&B singles in the States. But that is more an issue of space than poor track selection.

Recorded to benefit the Special Olympics, this has some of the biggest names in contemporary music, most covering seasonal favorites with mixed success. Outstanding tracks include The Pretenders "Have Yourself a Merry Little Christmas," with Chrissie Hynde giving a touching performance. Run-D.M.C.'s topical "Christmas in Hollis" relies heavily on sampling "Back Door Santa," and may head you toward the dance floor. Alison Moyet's stately version of "The Coventry Carol" is beautifully haunting. Only the Material Girl, Madonna, embarrasses herself with an overly campy "Santa Baby".

Whitney Houston became an international star with this album. It sold more than ten million copies around the world, yielded a string of number one hit singles across the board like "I Wanna Dance With Somebody (Who Loves Me)," "Didn't We Almost Have It All," and "Love Will Save the Day," and established Houston as the era's top female star. She later went on to more than solidify that status, with other hit albums and a budding film career. While this is a far cry from soul, it's the ultimate in polished, super-produced urban contemporary material.
