Let's face it the Stripped singles were a masterclass of a pop campaign. There wasn't a single weakling in the bunch, and whilst they had some lyrical themes running throughout there was so much sonic diversity in there. It's no wonder she couldn't ever top it because how could she?
It's crazy how irrelevant she feels these days. She was, arguably, in the early 00s, the most commercially-successful of Britney, Christina, Beyoncé and Pink, and yet they have all surpassed her many times over in terms of number of hits, classics and cultural impact.
"Ain't No Other Man" just wasn't worth the 3-year wait. Too long between albums and nowhere near good enough a song to kick off "Back To Basics" which got half of its sales off of the back of "Stripped" rather than its own merit if you ask me. "Back To Basics" had highlights but they launched with a song that wasn't good enough and "Candyman" as single #3 boxed it into novelty corner too quickly, even if it was moderately successful.
