_ been real quiet ever since this dropped

When someone releases a product (example: music) and someone states that someone who's known as being good at producing a product of that type (example: Eminem) has been real quiet ever since it dropped, meaning that the product was so good that it sent someone who is known to be good at it was silenced at it's greatness.

Person 1: *makes a really good rap song.*
Person 2: you know, _ been real quiet ever since this dropped. (Insert a really good rapper on the _)
