Not everybody rapped
In 2013, everybody and their grandma raps. Seriously, rapping grannies are all over YouTube. For every age, shape, size, race, ethnicity, nationality, religion, sexual orientation, educational background, and profession, there's somebody on a mic representing that. Inclusion, and using rap to express different POVs, should be a good thing, but the ubiquity of rap does have its downsides.
The element of surprise is lost. That first time you heard somebody who didn't fit your image of what a rapper looked or sounded like, it was mind-blowing and opened up a whole new world of possibilities. Now, if an 85-year-old bi-sexual albino midget from Papua New Guinea started kicking a verse, split open to reveal an alien, and that extraterrestrial kept right on rapping without skipping a beat, we'd shrug our shoulders. Meh. Saw that at Coachella five years ago, my dude.
Worse though, is that, with everybody rapping and able to record themselves and broadcast it on the Internet, there's zero quality control, nobody to make people think twice. A sea of wackness has watered down rap, and it only adds to our acceptance of horrible rap. Don't believe? Revisit the aforementioned rapping granny. Maybe we don't need to hear about how old folks get crunk.
