Is what happened last week between Frank Ocean, UMG and Apple game-changing? It certainly was for Universal, in that it triggered Lucian Grainge’s mandating an end to all exclusives—notably including a deal that had been in place between Apple, Lady Gaga and Interscope.
It's better for her to have the song on all streaming services since we are on the streaming era anyway. The only way she could benefit from a exclusive was having all banners on iTunes like Katy had with Rise.
Exclusive or not, if a song is set to be a smash, it will be. We can only hope that the GP likes it.
