I don't think any judgments should be passed until more promo and the video kicks in. I definitely expected the song to fall in sales since most of the sales were front-loaded due to Grammy exposure. If it continues to flop on iTunes after all of the above mentioned, then okay. But the song has only been out for a week.

and the majority of the uneducated general public probably didn't know the demo had leaked.
