Underwhelming vocal performance. Kelly just doesn't the sheer vocal power for Whitney's vocally challenging songs. As always, the pressed Kelly stans can't keep Beyonce's name out of their mouth. Kelly is NOT on Beyonce's vocal level and never will. Beyonce has tackled & covered far more versatile & vocally challenging songs than Kelly. 1 thing for certain, if Beyonce was to tackle this song, she would actually put the time & practice to get it right unlike Kelly's vocally lazy ass.
