Demi Lovato just might have a monster hit on her hands. This morning her new single "Heart Attack" went on sale a week early in an effort to head off unauthorized leaks. The result is that the song has roared straight to the top on the iTunes digital sales chart. "Heart Attack" has been well received by fans and critics alike. It should fit perfectly at mainstream pop radio which, along with the strong sales, should spell an instant hit. Demi Lovato's most recent album Unbroken included two platinum selling hit singles, "Skyscraper" and the chart topping radio hit "Give Your Heart a Break." Check out more about "Heart Attack" in the review below.
