I would have to say Britney Spears. Yeah she hasnt done great recently but shes the one who everyone wonders about.
Shes much more liked than Madonna ever was.
Please! Should I mention sales stats of 200 million albums sold, or the fact the Madonna has been going 20 years and had 63 Top 20 hits in the UK. Or the fact that she writes & produces her own stuff and sings live.
I feel very much for Britney on a personal level and she has had some good songs, but they've been written and produced for her and all she's done is turn up in a studio and lay down the vocals. Speaking of which...well, put it this way, I have never heard her sing live.
Sorry, didn't mean to be dismissive of an artist you like, but to say she's more liked than Madonna...
