Demi Lovato "Heart Attack" Teaser is Shortest Teaser of All Time, Sounds Good Though [LISTEN]

This infuriatingly tiny snippet of an upcoming Demi Lovato song called "Heart Attack" sounds promising.

The former Disney star posted the 4 second clip to her Soundcloud and though it's a bit fuzzy, we can make out a few things.

-Demi sounds good.
-There appears to be some major drum action. There's a few pounds before the song cuts out. Expect this one to be a banger.
-There may even be a dubstep-style drop, at least that's what it sounds like.
- Demi is going to sound big on this track, her vocals go into soaring territory right before the audio cuts out.

Dedicated Lovato fans will have to warm themselves next to this clip for a few weeks. The single doesn't drop until March 4.

What do you think? Does Demi sound awesome? Is it too little to go on? Is she a "rock star" now? Sound off in the comments and stick with Mstarz for all the latest news about Demi Lovato or other pop princesses.
