In a publicity release to promote the album, Furtado said: "This song came from a poem I wrote called Teenage Waste. When you're a teenager, you want to try everything; you're like a little firework. Your wiser self is there, somewhere deep down, depending on how young or old your soul is. But it doesn't always show itself. 'Explode' is visceral; it's guttural. That's why part of the song uses terms from Capoeira, the Brazilian martial arts form. It touches on teenage experimentation and bliss and fun, but also on some violence and aggression."
Most of the video is animated using the same drawing of Furtado that appears on the cover of the single. Furtado directed the video with Bradley Clayford.
"Sloop John B" is a traditional West Indian folk song, and it was a huge hit for The Beach Boys in 1966. They tweaked the lyric, "This is the worst trip since I've been born" to "...I've ever been on" as a wink to acid culture.
"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.
