Nah, by people, I mean people that worked on these same albums and told me who dude was and what he was doing. Or told me what the process is, with these albums now, with Kanye.
I was a huge Kanye fan, but just like other tracks that were pointed out in this thread, in the past decade or so, he's come out and said he's done beats he didn't even do. It wasn't until the actual producers came out and said what they did, that most people found out that they were involved. The days of Kanye sitting on the MPC and ASR-10 and actually banging out tracks, are mostly done.
Kanye isn't going to give credit to someone for a beat, if they didn't do it. He'll give himself credit for additional production, if he just talked on something, lol. But anyone that knows dude or someone who does, knows you're not getting credit for something you didn't do with him. AD has been credited as writing and producing songs that he said he sent Kanye. Just like Don Cannon was sending Kanye whole beats and getting "co-producer" credit when he did the whole beat. Kanye ain't in there cooking no more. Those days are over.
