I'm not a big fan of viet rap, but northern accent sounds better than southern imo.
Not a fan of rap either. However,
Either accent works with rap. This guys northern accent works well because it’s not too constrained. Northern accent with a strong clip is very incompatible with rap bc rap is about getting loose. Lose clothing, lazy enunciation.
Southern accent works too as long as the singer does not talk too nasally.
I think this one is a good example of southern accent going well in rap, what do you think?
