Beyonce, Adele, MJB, Whitney, Jennifer, Alicia, Mariah, Christina, Gaga, Pink etc are all singers, hell even Nicole Scherzinger has been known to belt on a good day.

Rihanna, Katy, Britney, Janet, Ciara are not singers, the are products that have gotten good at selling us something that brainwashes us into ignoring the fact that they can't sing.

I'm not saying we should hate these none singers [hell i love all of them] but even a drunk Mariah or whitney with her drugged up voice can sing these women into retirement, so please enough with the foolishness. If you think Rihanna etc can sing better than anyone u need ur brain checked
