Christina Aguilera's long-in-the-works album 'Bionic' debuted at number three on the Billboard charts. The record moved approximately 110,000 copies in its first week in release, marking the weakest launch yet for an Aguilera studio set and falling short of soundtracks for 'Twilight: Eclipse' and 'Glee.'

That's less than a third of what Aguilera's last album (a two-disc set, no less), 'Back to Basis,' sold in 2006. So what went wrong?

Well, a few things. Without a hit lead single to kick it off, interest in the disc was low, and Aguilera has been awash in bad press after canceling her summer tour and seemingly turning her back on her greatest asset, her multi-octave voice, in favor of electronic dance music that many critics felt was already dated by the time the album hit stores.
