The only reason why it came out of nowhere is because it already been getting preorders on iTunes for weeks now. No surprise there and because the radio deal this song has, I'm guessing that it'll also do well in the upcoming days. I think Austin'll be the next teen star for sure. He has the potential and this song is more than likely to be his breakthrough hit that he has been needing all along.
I wonder if it's going to be this song that radio officially latches on (after its radio deal is over). If so, Austin has a HIT on his hands.
