This acoustic lament about the end of a relationship is one of several songs on Shangri La where Bugg addresses romance. He explained to The Sun: "The only reason I wrote the songs was because I don't really talk about stuff like that."
Many fans suggest this song is about Bugg's short relationship with top model Cara Delevingne. Such lyrical allusions to dating a celebrity as "All the time people follow us where we go," and "all of these people want us to fail," appear to confirm this, though Bugg has declined to comment.
Bugg described American Idol as a "dream smasher" after performing this song on the show. The singer-songwriter told BBC's Newsbeat program that he was personally asked to perform by one of the judges. "It was quite sad," he said. "We ended up doing the show because one of the judges, Keith Urban, wanted us. [But] it's cruel. It's like, 'Thanks for coming on but you'll never get a contract.' It's the dream smasher."
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.
