Just because you want someone credited for a beat doesn't mean they are credited. 50 tracking down Apex is a totally different story. Anybody that knows how G-Unit conducted their business in regard to producers knows they did their research because they got their beats via A&R's. The A&R's fed G Unit beats off beat cd's, but didn't disclose the names because 50 didn't want to pick beats based off of a name.
D. Dot didn't just hand Nas a beat and called it a day. Did you even read the post? He was in the studio with Nas and aided in the creation of "Poppa Was A Playa". Kanye wasn't there for the session. Without D. Dot, the world doesn't have a "Poppa Was A Playa". That beat could've ended up anywhere. That's not stealing. Stealing would be D. Dot saying he did everything and Kanye didn't deserve credit for doing the beat.
You're going out of your way to discredit Dre.
