What you said sounds good but don't forget that the hiphop fans are the majority of there fan base and that the hiphop fans made them. Without the hiphop fans they may open some doors but they won't have a successful career as they can by abandoning their fanbase for the love of hipsters.
Breh...Outkast started some DBoy and Pimp shyt and they went all the way fukking left...and Andre 3000 started singing and rapping about some other shyt...
And Hip Hop fans didn't love them like that either...and they did just fine without Hip Hop embracing them...like it did Jay Z or Ja Rule or 50 Cent...
Motherfukkers like Russell Simmons even said Outkast ain't Hip Hop
Point is....
There are music fans...and there are Hip Hop fans...and there are Pop fans
If you are not a mainstream Hip Hop artist and yet you do Hip Hop music...most likely...your fans are either gonna be Hip Hop fans or all around music fans aka "Hipster"
And if you are someone like Vince or Danny Brown or Tyler the Creator...you'll probably get more money fukking with music fans....and people that just like you
Tyler the Creator, Danny Brown and Vince Staples and artists like them (talking Joey Purp,JPEGMAFIA) don't really need Hip Hop heads at this point...they don't get played on the radio...Hip Hop heads don't care for their production...they don't even use traditional Hip Hop producers...and they rarely get covered by Hip Hop media...
They can go on any of these Hipster festivals and get the bag...
They always gonna be rated as having as one of the top albums of the year by broader music media....like Rolling Stones, Complex, Pitchfork, AllMusic....because they are that revered and that groundbreaking for their genre...meanwhile all the motherfukkers Hip Hop heads wanna say have best album doesn't even rank...
The only thing that is Hip Hop about them is the genre of music that get classified in other than that they are outside of the ecosystem that majority of Hip Hop artists and fans live in...
