Genre of R&B Music

People have their particular genre's for music.  My style is Hip Hop/R&b, but more specifically, R&B.  The main artist i want to portray is Ne-yo.  And some of the surrounding artists include George Nozuka and Stevie Hoang.  Some of their similarities include: they have great voices for singing, use piano beats, and occasionally sing soul style music.  Their differences include their nationality:  Ne-yo is African American, George Nozuka is half Japanese and half canadian, and stevie hoang is Chinese.  It's crazy how no matter where you come from in the world, how similar and popular R&B music is.  Some more differences include how george nozuka and Ne-yo do pop music occasionally, but Stevie Hoang focuses more on hip hop and soul.
