Ralo is independent and paid the money himself out of pocket, there was no label to charge. he said felt it was worth it because it got him exposure. He said he paid because he don't want to ask anyone for shyt. In the interview he said "Future told me you 'gotta give me something lil bro, just throw me something. I charge 50-100.' " So Ralo gave him 20 bands for the song and 5 bands to do the video. I'm assuming that went in Future pockets.
I just never heard of someone charging someone on their team for a feature. If I am missing something fill me in.
He also mentioned the song had to be cleared from Epic. So it's possible label politics were involved.
