Howaaaaaaaa,,too many good songs that I really want to share to you. Tonight I'll make post about Demi Lovato's song which is called as Heart Attack. This song was released on 24th February 2013 as the lead single from her new album. It was written by Sean Douglas, Nikki Williams, Aaron Philips and her. William said that the song is about him that being really scared to fall in love again after being rejected, after feeling so fragile and vulnerable all the time, and thinking that he doesnt know if he ca do that again.
Below I put the lyric and link that will easier you to find the video :)
