Okay I understand that some of the votes are to troll, but Beyonce? I don't get how Beyonce can sing Bliss.. Her range goes up to Eb6, that's like almost a note short of the BEGINNING of whistler register.
Without the whistle parts, it may sound crazy but I could hear someone like Janet Jackson or Maxwell singing a song like this. Janet because she makes sensual songs like this and it's in a soft voice (her specialty lol) and the aura of this song is great for Maxwell's tone, and he could do falsetto
