Sorry, have to correct you there.
95% of all music today borrows from the blues in some way. Hip Hop was not even invented in any form until about 15 years ago.
And hip hop doesn't borrow from other music, it downright steals, "sampling" someone else's song is crap, which is why I rather that it was puff daddy that had been gunned down, instead of 2PAC, at least 2PAC was original.
Not everyone samples, and the ones that do have to pay to use the sample or get sued.
I agree that I would much rather have P Diddy dead than Pac, and that The Blues has been a major influence on all music. But add 5 yrs to the age of Hip-hop.
