Bon, apparemment, si MTV ne dit pas de la merde, le leak serait bien réel
"MTV News attempted to verify the leak with a spokesperson for Daft Punk's label, Columbia Records, but received a firm "no comment," though, a second source confirmed it was, in fact, the genuine radio edit of the single (and yes, things are so super-secretive when it comes to Daft Punk's Random Access Memories album that we're relying on anonymous sources)."
