It was never going to be an instant smash, you have to remember she's fighting an uphill battle right now, she's rebuilding her image and trying to win back the public, it takes time.
Radio and Spotify are building, streams are decent, I trust that the label know how to handle this.
This is still doing 2M a day on YouTube/Vevo. Streaming and radio is doing well we just gotta hope sales move up after promo in the next few weeks. I'm sure it will.
She would definitely need to do something next week to pick up her iTunes numbers though. Her debuting at 50 and then the next week falling would not be a cute look.
She seems confident that it will grow and radio seems to like it, so let me keep faith in this song because it is so good and I can see it being a summer song.
