First off bruh, don't ever tell me what I can't or should do on my internet
Second of all, if crack hadn't destroyed communities, families, and opportunities, then rappers wouldn't rap about it. Art always, reflects life. This is why in the 1970's you had Gil Scott record the Bottle , Grandmaster Flash with The Message in the 1980's, Tupac with Brenda's got a baby in the 90's and so on. If shyt wasn't already foul, then the artist in question wouldn't rap/produce music about what was transpiring. Now I do believe that artist do get put on more for making club-friendly music, however I do think the content of said song may be irrelevant because then how do you explain similar music that gets pushed, played like Flo Rida and LMFAO .
Third of all,


if you still need mainstream radio to spoon feed you music that isn't what you like, when you can go straight to the source (bandcamp, amazon, spotify, soundcloud) and support the artist in question that you like.
