I can tell you right now with 100% certainty that the label didn't leak it. I just got off the phone with them and they're REALLY unhappy about it, so... if this was their "plan" they're doing a good job of following through with it.
No real news on dates, though. Everyone I spoke to (from label or otherwise) were pretty unwilling to give anything up. But I WILL say that they really, REALLY appreciate everyone working hard to keep it under control. Our reporting isn't going unnoticed and they're doing everything in their power to control it, but once something's out, it's out. Beyoncé herself isn't ready JUST yet, which is why nothing has been done. But they're well aware of what's happened and what's going on, so hopefully they/she do some shifting and something is done SOON.
I shared it with other Beyonce fans JUST LIKE everyone on else was sharing this song before it got leaked....
You can't share with it any and every ****ing Beyonce "fan" because you don't know what they'll do with the track. Ugh, this is why I don't use low tier "fans".
