In 2003, Hip-Hop dominated the Billboard charts. In 2006, High School Musical ruled. What in the Sam Hill happened?
Well, I noticed that guys like Chingy and Akon were making new music instead of people with talent. Meanwhile, the people with talent were busy selling clothes with names like RocaWear, Ecko, and Apple Bottom.
In other words, the best (and business savvy) stars like Jay-Z, Eminem, and Nelly have figured out that they can make more money not making music. So the best music talent is getting paid to do non-musical things. If Elvis would have gotten a cut off of those ceramic plates, he wouldn't have had to keep touring as an overweight 40 something.
So while Hip-Hop music is suffering, Hip-Hop culture is spreading. But if the quality of music keeps dropping (not like it's hot), will the culture continue to spread?
