To me, I won't say "most" but I will say a lot of New York beats sound the same to me. There's just no motivation in New York beats. When I hear a West Coast beat like Dr. Dre, Johnny J, QD3, DJ Pooh, Warren G., Scott Storch, Eminem (yeah, he lives in the midwest but is considered WC), Daz Dillinger and the like, that shit motivates me. It gets me bobbing my head like a mofo. It puts some spirit in me, makes me a little more lively.
However, when I hear A LOT of New York beats, they LITERALLY make me tired, they make me wanna fall asleep. They have no motivations qualities whatsoever.
