You know, I can understand all the negativity towards hip hop, the culture, and the artists. It's already instilled in your objective brains that anyone from hip hop (and probably black) will fall under weak critical analysis such as yours. It just baffles me how people lieky ou can hate with so much confidence when you are so off base from the truth.
50 was thirsty after a workout and went to the market to buy a drink. He wanted water with vitamins. Looked around to see if anyone had thought of a product like this, then he ran into Vitamin Water. After that he bought 10% of the company (obviously after research, advice from his team, financial managers, etc). Shortly after that they were bought for 4 billion by Coca Cola.
So in short, he found vitamin water before they found him. Your little made up story of a guy in a suit coming up to him as a potential investor is incorrect, but it's already instilled in your mind that he's a rapper so he couldn't have had any creative part in it.
It's ignorance such as yours that is a shame. Doesn't matter though, those writing checks knows that these hip hop artists are better brand images than the artists your interested in.
Socrates was told by an oracle that he was the wisest man in the world. He didn't believe him so he went on a mission to find someone wiser than him. He couldn't and realize he was. All the people he talked to had such strong opinions and certainty about things they knew absolutely nothing about. Socrates realize that his edge over everyone was that he knew that he knew nothing.
Unfortunately, the head-fi community (earphone, headphone, sound enthusiasts) is filled with people like this.
