Neon Trees' Pop Psychology album has a loose theme about the challenges of finding love in the digital age. The album's anthemic opener finds vocalist Tyler Glenn yearning for a pre-social media connection. "You can hear my frustration with turning 30 and not being totally excited that I'm still single," he said, "but also realizing that I had to first own who I am and what I want before I can truly find someone."
"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.
