Demi Lovato 'Heart Attack' Official Release [LISTEN]: Debut Crashes Ryan Seacrest's Website

Earlier this week we showed you the insanely short teaser for Demi Lovato's comeback single Heart Attack. Well apparently the leaked, low-quality soundbite garnered enough interest to convince the former Disney starlet to release her single early and it is quite the banger.

The track got people so excited that it actually crashed Ryan Seacrest's website, where the track was officially debuted.

The pounding track features a healthy dose of drum and bass, skittering guitar riffs, soaring vocals that could easily be described as Kelly Clarkson-esque and awesome vocal glitches to keep it interesting.

Check out the track below and let us know what you think in the comments.

Do you like the song? Do you like the new Demi Lovato?

Is this new sound working for her? How about that cover art, eh?
