Christina Aguilera At #11 On 'Best Of 2010'

The much-delayed sixth studio album from Christina Aguilera saw the blonde bombshell, once the queen of risqué pop videos and all-out dancefloor fillers, apparently playing catch-up with last year's most scrobbled artist, Lady Gaga.

For Bionic, Aguilera hooked up with a dream team of producers and songwriters - from long-time collaborator Linda Perry and hit-maker Tricky Stewart to a selection of more leftfield choices - in an effort to branch out into unexpected styles. Le Tigre and Peaches contributed their trademark noisy electropunk on 'My Girls', while arch Liverpudlians Ladytron provided 'Birds of Prey' on the deluxe edition of the album.

The lead single from the album, 'Not Myself Tonight', shot straight to the top of Aguilera's chart, with over 1.7 million scrobbles since its release in April. The pounding dance track had you pressing repeat throughout the year, leaving the rest of the songs on the album trailing behind in comparison.

Nevertheless, perching on the edge of the top ten, Bionic proved to be one of the year's major albums despite not quite living up to Aguilera's previous commercial success.
