Because Future did the melody? Detail either ****ed him over and didn't mention it to Beyonce's camp, or they just didn't care enough. Beyonce did her vocal based on his demo so how could she remain completely unaware of his involvement? Especially when Detail told Future that she liked the way he did his melodies. She was specifically looking for a sound like his, received it, and then gave him no credit whatsoever.
I do think Detail ****ed him over and presented it as his own. Bey gave some of the most obscure people their rightful credit like Polachek and Boots. If she was so against giving credit, she could have gotten them as ghost writers/producers.
She's smart enough to be richer than you and all the people she steals from.
Lol that means nothing.
I don't get why the Hive just can't accept Bey for what she is. Every stanbase is the same in their own different ways but this need to make Bey out to be this talented writer and creative artist is so laughable. She's not. That's the truth. Accept it or stay deluded.
How often does a demo singer (who doesn't write nor produce the song) get credit?
Never.
Although, Future did do more than a typical demo singer by helping with the melody with Detail, but that was a favor, and favors are not always credited.
