21 Savage very effectively rides on his vocal tones, I've never been disappointed to hear him in a song. So really there's no surprise that he can hold his own...on his own. "Bank Account" makes for an effective single as it has a distinct hook which also manages to be completely child friendly. Most importantly though it is a very good meme template. The slight shift when the bass drops back in during that hook always spins me out in the best way.
