rap is huge not just among asian americans but in asia itself. i have a korean friend who showed me k-pop songs to show how big rap is in korea. low key every girl k-pop group has one girl whos the "rapper"
theres also a korean game show called show me the money where rappers compete against each other
but he said theres also an underground scene where they listen to wu tang and nas all day and look down on mainstream korean rap
as far as blowing in the US eventually there will be an asian lil pump or 6ix9ine eventually.
