You couldn't be more wrong. Not to mention that your post is incredibly classist and even subconsciously racist.
I'm about to graduate from college with a BA in English, and I can greatly appreciate the lyrics of many, many rap artists. Hell, my sister's in postgrad law school at University of Chicago, and she will sit down and actually listen to the lyrics of rap songs.
Many people I know, including some of the whitest living-in-the-country people you'll ever see, not only appreciate the musical aspect of rap but its lyrical aspects as well. If you have an analytical mind that can actually get past a few reiterations of the word "fuck," you can hear that many rap songs are about personal struggle, emotional turmoil and achievement. Just because zykO's lyrics don't read like an after-school special doesn't mean the spirit of camaraderie, struggle and friendship isn't there. Believe it or not, words can have more than one level of perception to them! There's a little something called "subtext" you might want to get to know.
And if you refuse to believe that people of intelligence and sensitivity can identify with rap, you're simply denying the validity of an art form because of your snotty personal opinion and blatant classism.
