Gaga has a better voice than Beyoncé, Brandy, Jill Scott, but cannot be compared to Carey or Aguillera. They are different genres. GAGA is by far more creative and more entertaining and has a very powerful voice. Tons of people out there have great voices, but they seem not to crack it because you need more than a voice, and Gaga has that. She is one note. Christina and Mariah are one note.
