This upbeat, feel-good tune holds a special place for Caroline Hjelt and Aino Jawo as it was the first song they wrote when they got together in 2012. The Icona Pop duo finally recorded a version of the tune for inclusion on their Emergency EP. "It's such a special song to us and really is a celebration of friendship, whether it's with your boyfriend or girlfriend or best friend," Hjelt said. "We just wanted to capture that feeling again in a song and remind ourselves how important it is to never forget those special early days when you first meet someone."
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.
