Eh, because hes not. Buying the label hype didn't make Bono talented. In fact, in an interview I had seen some years back, the musically talented members of the band were being interviewed. The band had already formed and was looking for a singer. They talent search was "extensive"...that is to say, they held a tryout at their high school. Of just the members of that school, he was only the fifth best singer (find any real vocalist and they will tell you how miserably unskilled Bono is). They couldn't decide who amongst the leading four should be hired and had some disagreements about it. One day the one who used to wear the flattop realized that what the band was missing and was needed in a front man was charisma. When he brought that to the bands attention they all agreed on Bono.
No real talent, just "charisma" and label hype.
Sounds a lot like Obama.
