This was the second song Halestorm wrote for Into the Wild Life and it's groove was something that they've never really done before. Guitarist Joe Hottinger commented to TeamRock: "To me the song's like cruise control. It reminds me of a sunny day in California, driving along with the top down and the music blasting. It's one gear, which maintains the same throughout, and it just feels good. It's New Modern Love, man. It's more of this 'do what I want' sort of thing."
Frontwoman Lzzy Hale wrote the song about her brother/bandmate Arejay's relationship with his now-wife, Jessie Covets of true Violet. "We're both musicians and the relationship is very chaotic," he laughed to Kerrang.
"Kickstart My Heart" is about all the ways Motley Crue gets their blood flowing without drugs. It was inspired by their bass player Nikki Sixx, who claimed he had to be revived with a shot of adrenaline to the heart after an overdose.
