2 – Are you sure you downloaded the main file or just the preview?
Same happens here some times. Ok, last time I’ve seen that was one or two weeks ago, now it’s better.
I don’t think that “famous” is the right word, but, I guess I can say “I’m well known internationally”, as in, my mom knows me very well and she is in Romania, my wife’s family knows me and they are in Lithuania, and my friends from Norway also know me, so… internationally… unintentionally… known… by less than 10 people…
Well, at least a bot got in love with your avatar pic and wanted to get more personal, not just some bank manager (which is always from Burkina-Faso for some reason) wants to sent you several trillions of thousand…

You might have to layer up more than one synth. A bit of portamento, a bit of distortion and you’ll be pretty close (I guess).
I can say just from my point of view, which is listening on my headphones 
So, the mixing sounds very good to my ears, more like dubstep than hip-hop but keeping in mind that styles are evolving and crossing borders all the time, this might not be the issue.
What to my ears might be an issue is that in some places some melody lines are very close to be considered “clashing”. In some places the melodies use notes from tonality but the “down beat” doesn’t feel like is part of the chord played, so, maybe double checking that would fix the problem?
My only ukulele track doesn’t sell at all… I don’t know who is on AJ anymore
