I know I'm few days late to this but I can't help it that I was away for vacation.
Anyway, I'm very disappointed. I mean, you don't announce the date and then shortly after, say that you're postponing it. I know she said it was because the album wasn't ready but if they actually pushed this back because #Beautiful is stalling (and starting to fall a bit) on radio, then that's really stupid. That's their own damn fault for not pushing hard enough on the radio. They also should've released the remixes A LONG TIME AGO.
But if the remixes doesn't help the song right now, then the best they can do is release the second single.
The latest they should push this back is to August. It's not a good idea to waste a lot of time from the initial hype this had.
