Stop it. Acid Rap was an overnight success. He went from literal obscurity to taking pics with Madonna, being written up in major media outlets (not just rap media btw) and was all over MTV. I'm not detracting from his skills and ability to connect with his fanbase, because that's all him, but there is no precedent to that level of overnight success.
Even Drake had to bubble from Comeback Season to So Far Gone, doing guest verses, mini-tours etc. Wiz had to drop tons of mixtapes to get to the point where he took off. Kendrick gradually gained exposure. It's like a switch was flicked, Chance (who?) drops a mixtape and is suddenly a superstar. Not even Odd Future blew that fast, it still took a few tapes and controversial videos/performances.
The industry is shifting and trying new things, and I don't blame them honestly...
