Hope they signed some kind of paperwork....from the interview I saw it didn't sound like James placed too much regard/care for who produced that beat. This might be the first mainstream example of the clause "No royalties owed until X amount of units sold" coming into play as far as "leasing" goes.
Nah, he'll receive royalties as long as he registers the song. Him getting an advance is another story. But no one knew that song would blow up like it did.
