No difference, both are just disgraceful attempt to make something good (doubt they tried).
One retard turnt doing that mumbling shit and thought it's very good 'cause people with mental retardness supported that, and people like Uzi followed his way.
There is a fairly big difference between trap rap and dance pop. Not my fault that you cannot understand it.

i honestly dont listend to rap. I just simply dont like rapping as a form of music but objectively what songs acomplish and why they are written there are good rap songs. I can listen to some satirical/comical serbian/croatian rap but that is mostly it
