A lot of the comments have been hating on hip-hop, and well, I can't say I blame them. Most of the stuff you hear is just the same old shit. Some boring harmony over a lifeless beat and some lyrics that are so dishonest that it's almost offensive. But then you get some people who take hip-hop and turn it into something wonderful.
There are/were quite a few jazz guys who are taking the chill groove of hip-hop and fusing it with jazz, adding beautiful harmonies and some honest expression. In the 90's there was Branford Marsalis and his group Buckshot LeFonque who mixed jazz, funk, hip-hop, rock and pop. The Dirty Dozen Brass Band fuse the New Orleans brass band sound with just about everything they encounter, including hip-hop (probably best heard on their album What's Going On?). Trumpeter Roy Hargrove has The RH Factor, who deal in a dirty club type of groove.
Then there are guys like Robert Glasper or Jason Lindner who seem to play a more modern jazz with a heavy hip-hop influence. More adventurous harmonic and rhythmic devices, more of an improvised nature, generally smaller groups, but still with that same spacious and cool feel, played in a way that someone could rap over top.
If you think you hate hip-hop but love beautiful, honest music then I implore you to check out some of these groups. They may spark an interest in the genre that will lead you to search for more... of course, when you come across some guy singing about his drugs, money and women, it's perfectly fine to politely tell him to fuck off. Just don't let those arseholes stop you from listening to good music, whatever genre they happen to be polluting.
