Yeah B you know how I feel about the neptunes. At first I really hated them for the same reason I hated Eminem. The music was just annoying. Then once you start assessing the musical side of it, you realize there is just more than " trash can , bang on coke cans" production. Even though the style is simple, the shit gets you movin and noddin your head. I also agree that some ( 50%) of the beats sound exactly the same and the formula gets tired. Saying that though look at the history of the neptunes. They have made so many hit songs that define the late 90's and the 2000's. They were the " go to" producers for a hit song, but now I think it is Lil Jon and Dr Dre.
