And also, with rap there are just as many songs less about the message and more about the story. Let's take a couple of famous songs for example, Stan by Eminem and Today Was a Good Day by Ice Cube. Both are vivid image provoking songs about a in the case of Stan an obsessive fan and in the case of TWAGD it's just a chill rapping about a good day. If you find stories boring then you would be bored with everything, from books to TV shows to plots in games, to maybe even your own life.
I never once said I found stories boring, so please don't try to put words in my mouth; I'm quite capable of speaking for myself.
Well, here's my life-experiences with Rap.
Most (not all) of the rap I'm exposed to is played for one of these reasons:
1) It (allegedly) makes the person playing it "more badass". They usually blast the Bass and ignore the rest of the track, which seems silly to me, but then again I don't 'get' this stuff. I have a friend who was a music major, and the best explanation I managed to get out of him was "Bass is euphoric."
Personally, I find compositions to be euphoric. Different strokes? I dunno.
2) It's rebellious or self-glorifying "gangsta" stuff. Surviving the streets is one thing I can respect (I'm not street-material, and never claimed to be, but I have friends who are); bragging about being a criminal is something else. It's not something I would hope anyone to want to openly aspire to, and it's definitely nothing to be proud of.
3) It happens to be on a paid-to-play playlist on the radio. Most of this sounds like it was manufactured and is usually driven by the star power, not the message.
4) It's sexual innuendo. "Raunchy/shocking" stops being effective when one lives in a culture dedicated to implying double-meanings in virtually everything.
5) It's silly nonsense some companies use to try to look more "hip". You know the stuff (and if you don't, then I truly envy you).
So pardon my bias, but for the most part I only ever get to hear the obnoxious stuff (described above), and I have absolutely no idea where to start to look for the good stuff.
Said music major friend is a big fan of Rap, and even the best stuff he demoed for me falls primarily into categories 2 and 3.
