Rihanna is by far the most embarrassing excuse for a 'popstar' to ever exist. Absolutely no vocal talent or stage presence, no input whatsoever on her albums, and 100% NO media coverage whatsoever, even when she literally went topless on the red carpet. Stupid Bajan ***** who's never releasing another album.
Rihanna strikes me as much more "useless" than Katy Perry who seems autonomous and driven despite seeking and relying on others expertise. But R has one of the best studio pop + hook voices ever.
