In reply to I STAN(D) FOR TALENT.

@Rihboy like when Sia sang the majority of 'Diamond's' chorus and background harmonies but only got credits as being a co-writer on the song, as if she wasn't the one who carried Rihanna on her OWN song. BYE. at the very least, Beyonce sings all of her own un-altered vocals and when she does invite someone to harmonise with her they get a 'featuring' credit or 'background vocalist' credit.
