Sales don't matter to me, it's a dope project. But my takeaway is
1) Thugger is not making strides with the mainstream (white people), nor is he really fostering a loyal fanbase. He's good for 14-18k sales based on his last few projects.
2) Not selling doesn't mean you aren't popping...but stagnant or decreasing sales suggests you aren't growing
3) Future transcended the typical "club rapper" trappings whereas Thugger hasn't
4) I think this is partially because he is terrible live and can't really perform decently. It's hard to build a true following if you aren't touring consistently. Thugger is largely a studio creation when it comes to his vocals, the engineering, etc. It's hard to gain popularity if the people don't see you. Not everyone is The Beatles, who largely became a "studio band" with the later/better albums and stopped touring consistently. It didn't matter, they were still popular. This is 2016 tho and rap, that's not gonna fly.
