50 years of Hip Hop- How Come?

If Hip Hop has survived 50 years (I'm not qualified to answer that question. I can't even identify what makes a "song" Hip Hop), it is for the same reason every other genre has survived in time: there is an audience for it. It's no different than in 2000 or so Rock 'n' Roll could have been said to have lasted 50 years, which many older people in the 1950's didn't expect. Have you seen the clip of Frank Sinatra denigrating the 50's Rock 'n' Roll singers?

I love spicy food, my sister likes her's mild. In the world of Classical music my first love is the Baroque era (not that I don't love Beethoven, Wagner, and Rachmaninoff), a really fine bassist I played with likes Classical and Romantic more. Taste is taste, that's why, as the old joke goes, they make ice cream in different flavours. 

I like Schumann, but not all Schumann.

I like John Williams, but not all John Williams (Happy Birthday by the way! 🎉)

I like John Coletrane, but not all John Coletrane.

I like Glass Animals, but not all Glass Animals.

I like Snoop Dogg, but not all Snoop Dogg.

I like music, but not all music…(and that’s ok)

arguably, recognizable rock and roll music was being produced as far back as the 40s, cab calloway even referenced it. in light of this particular longevity, it is well-understandable that hip hop/rap and its variants would survive 50+ years.

Don’t really get it. What was new with Punk, New Wave or Grunge?
To me the new is that billions of artists can reach you through just a push on the button. 

Human beings like to classify stuff. I think the word "genre" is just French for classification. So much modern music is a blend of genres. Modern R&B has many elements of Electronica. I hear Jazz infused Hip Hop. Even some Country has elements of Urban (read Black music) elements. Some Rap has elements of Electronica and even Jazz phrasing. Its a wonderful mish-mosh, which is elemental to "American" music.

I now enjoy listening to World music. I hear a lot of very cool electronica in Middle-Eastern and Indian music. Not to mention the influence of Reggae on African music.

I suggest streaming the "Station" World Revolutions, one of the three streams on World Fusion Radio. Although its only 320 kbps, it's very listenable, even on an elevated sound system. He does request donations.
