Rap used to be "cool", it used to "feel" "dangerous" sorta like metal. 
Now it's GAY as fuck.
Instead of Biggie, we have Drake crying all the time and fuckin cunny.
Instead of Pac, we have a million Negros trying hard to be profound like Pac and mostly failing.
N.W.A was replaced with fruits.
Instead of Missy Eliot, we have a million bitches with 0 actual talent beyond sex appeal. 
On top of that, modern "rap" has been fused with RnB, techno, and Pop. it no longer "feels" like music from people who lived a shit life. It feels like music by spoiled shits.
