This song finds Hayden Thorpe and Tom Fleming singing of a dream state, halfway between asleep and awake over picked guitars and sparse synth. Fleming told NME: "This has a very clean guitar and synth, which we were careful not to overuse. When we sat down to record this album, we realized, 'This wants to be a pop record now.'"
Hayden Thorpe told DIY magazine the tune went through a huge amount of versions. "We almost wrote it off," he said. "We just couldn't get it right. The barometer was flinging either from being this Ibiza thing straight back into this song you couldn't focus on. And we couldn't get it to level out. Like most moments on the record, when we had half an hour of demo time left we scrapped what we had and started again. Within half an hour the dual guitar line came about."
"The song itself has been around for a long time," Thorpe continued. It's about euthanasia, really. What I think a beautiful pop song should be able to do is take a very difficult subject and make it sound completely weightless; throw it up in the air like it's a feather. That's what I wanted 'Sweet Spot' to do. This might sound morbid, but the song also refers to how death and sex are from the same creature. It's the snake's head and the snake's tail."
"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.
