Not all rapping is shitty? That's a pretty ignorant statement, and FYI, your beat isn't even half-way decent. How about you make an actual good sounding beat and add some of that "shitty rapping" and people might actually listen.
It needs more elements to it, like brass, strings, white noise, transitions, FX modulation etc. That synth gets very repetitive, and uninteresting. I know it sounds really complicated, but if you were to look at the project files for charting songs, especially Trap, it ultimately comes down to structure, timing, and sound selection, with precise effects. Good effort though, it definitely sounds like trap, just keep on trying new things and let your creativity go, you'll find your groove.
