The 'Give Your Heart a Break' musician has released another intense track, although this song feels more electric than her previous material. The electro-pop track is full of EDM, club-like beats and is powered by drums, a bass, and an infectious guitar track. Lovato's maturing voice is very strong here, especially in the chorus. The lyrics and intensity in her voice mirrors Kelly Clarkson and shows off her impressive range. 'Heart Attack' is undoubtedly her most passionate song of her young career and indicates Lovato is poised for a highly-acclaimed fourth album. The single is about taking the risk of falling in love. She sings in the song: "You make me glow, but I cover up/Won't let it show, so I'm puttin' my defenses up."
The currently untitled fourth album is due out some time in 2013. Her first three albums have all cracked the top five of the Billboard 200. 'Heart attack' indicates this time around will be no different for the 20-year-old. Listen to the explosive single right now on AOL Radio's Fresh 40.
