i haven't really listened to much music out of this area for longest but anyway, in general, rappers should do what's natural for them and not have some preset formula. like going in there thinking "i need a trap rap song, i need a based music song, i need douche/bro rap club song, i need a khalifa weed song, i need a kanye appeal to pitchfork hipster folks song" just do you.
like what is your expectation of this besides "a classic" you tryna blow big appeal to the masses or you trying to satisfy to core audience or are you just trying to make the best music that's true to you? i guess i'm getting older but i've realized it is getting kinna stagnant and tiring when you have ONE producer do every damn thing. i can understand some folks who are just starting out, its economical to just get your bruh bruh to do it.............but then you got folks who scour soundclick and other shit to get some vybes or johnny julliano beats or even teef them with the tags still in it. i'm rambling here now but basically do what feels normal to you and not forced product.
i'd like to add, for content, talk about things that's true to you or want to speak on and not just cause you feel its a gimmick and need "that one song about state of hiphop" or that "illuminati is taking over" or even "the hood taking me under" cause you wanna make your damn album a swiss army knife and do everything. nah, do whats true to your heart with the creativity and it'll come out less robotic, forced and cheesy.
