This song was written by singer Win Butler and his wife Regine Chassagne. Though deeply metaphorical and with a number of different interpretations, the initial inspiration for the song's lyrics came from Chassagne's experiences with the North American ice storm in 1998. She was living in Montreal at the time, and the ice storm left the city in darkness for over a week.
Angus Young created the distinctive opening guitar part for "Thuderstruck" by playing with all the strings taped up, except the B. He learned the studio trick from his older brother George Young, who was the rhythm guitarist for The Easybeats.
"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.
