Editors' Notes Clocking in at 35 songs, Number Ones is the complete guide to Janet Jackson's biggest and best. From the saucy electro-pop of early hits like the flirty "When I Think of You" to the assertive funk of 2008's sexy "Feedback", it covers more than two decades of a highly creative and deeply personal musical journey. Key collaborations with jazz-pop pioneer Herb Alpert, iconic singer/songwriter Joni Mitchell, R&B legend Luther Vandross, high-octane rapper Nelly and her brother Michael showcase Janet's status as pop royalty.
