Several media outlets noted the absence of ' Can't Hold Us Down' from the compilation. The compilation also included Aguilera's 'professional and sexual coming-of-age' songs from her 2002 studio album Stripped including: ' Dirrty', ' Fighter' and ' Beautiful'. The compilation continues with her 2001 collaborations ' Lady Marmalade' and ' Nobody Wants to Be Lonely' the former with Pink, Lil' Kim, Mýa and the latter with Ricky Martin. Released in November 2008, Keeps Gettin' Better: A Decade of Hits opens with Aguilera's 'early chart-toppers' and first four singles: ' Genie In a Bottle', ' What a Girl Wants', ' I Turn To You' and the radio version of ' Come On Over (All I Want Is You)', all from her self-titled debut album. During an interview with the Los Angeles Times, Aguilera explained that Target 'got such a great creative team', and that's why she worked with the retailer for the album.

People who pre-ordered the compilation would receive a free digital download version of the single ' Keeps Gettin' Better'.
