Hip-hop and rap are nothing more than aggressive and yet monotone lyrics, set to simplistic beats and melodies. They take very little skill or hard work to create and are subsequently enjoyed by those with no appreciation of skill or hard work.
Also, hip-hop and rap tend to be something of a catalyst for violent acts committed by these unintelligent, uninspired, unskilled and lazy people (mostly men). Ironically, were one to resort to violence in an attempt to remove said-problem (I can think of a few who'd be first to go), this would negate the argument, entirely. So, the rest of us just put up with hip-hop, rap and their followers.
There are so many wondrous things we've learned we can do with our voices, in unison, with other hard-working people who've been practicing until their fingers bleed, and there are STILL those who listen to people talking over a generic melody and beat? Don't you KNOW this?
Those who "create" rap and hip-hop are an affront to civilization. They're the proverbial "slap to the face" to every man, woman and child who's pushed themselves beyond limits previously thought unimaginable, to achieve heights of success one could only dream of.
Those who willingly listen to rap and/or hip-hop, are the most dangerous of miscreants - examples of de-evolution. In essence, they're "regressing" back to their monkey state and, in my humble opinion, should be put down so as not to infest others with their disease. Ironic, really, since doing exactly that would be going against the argument in the second paragraph.
I genuinely hope humanity can recover from the plague that rap and hip-hop brought forth, but the more logical part of my brain knows it's truly a lost cause.>tl;dr: rap and hip-hop are crap.
