Now, I'll be the first to admit that I'm not 100% sure about all the origins to Rap, Hip-Hop, R&B, etc.
However, I do know that back in the days when Rap was just becoming mainstream, it was, as a whole, just as talentless as it seems to be now. I actually don't even listen to Rap anymore and even when I did, I didn't really enjoy it all that much. But this is something I think that has a valid point in music today. As there have been in every genre of music, some Rap artists were actually talented. Rap was just getting it's start though, so it's overall lack of talent, and originality was not to be so hard-pressed as it is now.
As Rap grew into a more modern, familiar sound, more artists started to emerge on the forefront of the rap scene. One's that stood out included, Tupac Shakur, and the likes. Tupac revolutionized Rap because he was the first to write words that weren't about the usual things that were being talked about in Rap songs at the time. Drugs, and killing people... gang banging to put it short. Tupac did Rap about many of these things, but his ability to write so many other kinds of words is what made him who he has become today. He carried a generation of sound that was trying to develop into "real" music. With his death, however, that first step was lost, and all that followed was the same line of boring, overused themes.
Rap is now more popular than ever, but is that really good for Rap as a whole? Popular, isn't always good. Look at "Pop" music, as it's defined by society today. No one remembers anything anyone does in the genre of pop. Britney Spears will most certainly not have a single song anyone can remember how to sing, or even hum in ten or fifteen years. Sure, they'll remember her, but her music will be quickly forgotten. So will Rap fall into the "Pop" deathtrap. If it continues the way it's going, yes, without a doubt. Rap lyrics have gone from bad, to worse over the past five years and there have been few people that have the ability to save it. But if there is anyone, it would probably be Emeniem. Who would have thought, a white boy may be the one to save Rap from becoming the same kind of joke that "Pop" music is. Emeniem is scarily similar to 2pac in that he doesn't rap about the usual "Rap" lyrics. He writes about many different things, and many of those things are themes that aren't usually ever tried in Rap. His ability, just like 2Pac's, to write about new and different things is what makes him one of the few people who can save Rap.
Rap... it's not something I've ever really liked, but it's something that is in our culture, whether we like it or not. And while I don't listen to it much, it pains me to hear something I actually do like and know that it won't get airplay because it's not about "Dem Bitches" and "Dem Ho's". What will Rap become you ask?? Only time will tell.
