if she's maybe performing "Try" on the VMAs, maybe they're waiting to release snippets until after her performance.
This. They want the song to sound fresh. And I hate the Itunes preview. 1 and a half minute is too much but at the same time not enough. LOL. I'd use the 30 sec snippets as an appetizer and wait one more week till the whole album.
I'm genuinely shocked we don't have them right now though. Considering the album is streaming on at least one outlet on the 10th September and we've not heard a single clip is weird.
