There is in fact elitism in the hip hop world however I think there is a line between being "open minded" and listening to bad music and just calling it different. Because just calling it different is to cover up for its lack of skill. For example I would say, and yes its my opinion, that the current form of Lil B makes BAD music. Not because of subject matter, not because he's OVERLY repetitive, or because on some songs there's no hooks and just rambling, and not because he speaks on different things like homosexuality and satonic matter.
Its because his execution and his skill is just terrible. There's no dynamic in his song writing, he's just bad.
Sorry to go on a rant about Lil B but he's just the obvious example. There's less obvious examples where fans make excuses for the artists actual artistry by saying they listen to a variety of stuff.
Listening to variety would be listening to John Lennon and Ice Cube. Not Rick Ross and Madonna.
I agree with your point though for the most part. But some criticism from boom bap evangelists is valid. I wouldn't call myself one though. There is still great music in the mainstream and in the streets. For example I think Hustle Hard is one of the Top 10 songs of the whole decade. It involves rebellion, struggle, and flaunting and valuing possessions and LOTS OF BASS!!! Its the essence of hip hop. Most
hardcore boom bappers would disagree but that song talks about struggle AND bumps at a party AND in a car. How many songs can do all three?
