The thing is Mariah chose to name two of her friends and that´s it. It was an irrelevant interview. I´m with the person who said Beyonce´s voice is not unique and doesn´t blow your mind like Mariah, whitney, celine and others do or did. She is very good and has control but is nowhere near those divas. For example Xtina is much more unique, but her screaming is just awful. And Celine´s voice went too nasal years ago but in the 90´s it was out of this world, not that versatile as Mariah´s or Whitney´s though. The thing is nowadays there is no mainstream diva with that total package voice like Mariah, Whitney or Celine. And among the 3 Mariah is now the more relevant even if some people don´t like it. Why? Cos she is still doing great music, is the more functional among those 3 now. It doesn´t make her better or something, it is simply a fact. Whitney and Celine will forever be legends no matter what too.
