Oh, and I want to clear something up. High-school dance music is not hip-hop. Ever. It usually isn't even real gangster rap. Tupac Shakur and Notorious B.I.G. are hip-hop. N.W.A (along with most stuff Dr. Drey does) is gangster rap. "Solja Boy up in them hos" is a male masturbation fantasy set to a synth drum beat.
And I'm a Jewish computer-science major.
That's just my opinion of what passes for popular hip-hop nowadays. This is formed after basically growing up listening to hip-hop.
When I was young and got bussed into school, the drivers were all from the black ghetto town a town over from me, so they always played "Hot 97" (New York City's "Blazing Hip-Hop and R&B") on the radios. Nobody had iPods in those days, so I actually got exposed to a wide variety of hip-hop and rap.
Back then I thought most of it was total crap, but I learned to appreciate a few groups. I especially liked songs that included instrumental riffs and real melodies. Today hip-hop's my favorite musical genre, even though nobody has heard of my favorite group because their only American concerts were/are on Christmas Eve (Brooklyn) or this month (West Coast).
Point is, I'd like to hear what exposure and tastes the rest of the XKCD boards have had to what is actually a solid, well-established genre of music that most people still, for some reason, consider the sole domain of impoverished American blacks and hormone-charged high-school kids. Hell, I'm thinking of how a "Hip-Hop Hero" video game might be made.
Reminder: Hip-hop, as defined on Wikipedia, mainly consists of 4 skills: DJing, rapping, break-dancing, and beat-boxing. If you perform using those techniques, you're technically making hip-hop.
