Not bashing or anything, but I don't think Beyonce has a huge following outside the US before IASF. And when IASF was released, she had a fierce competition with Lady Gaga's The Fame. And the more mainstream sounding "Fame" prevailed over the mere R&B "Sasha". What I mean is Beyonce's songs are not so mainstream globally, added the fact that she had some tough competition during her peak, Sasha Fierce era.
What's the point of Grammys? I mean, does 16 Grammy awards certify Beyonce as a better artist and vocalist than let's say the artist listed at #1 on this list?
