I used to get annoyed by Rihanna's voice, but now I LOVE her voice, it's so resonant and so powerful lately - especially her deeper timbre in Diamonds..
I really tried to love Beyonce's voice, but I just couldn't. Her voice sounds like an annoying trumpet, especially the frequency and timbre of her singing voice is high.
People say Nicki has an annoying voice, I think she has an awesome voice.
