This song was written and originally recorded by Willie Nelson on his 1990 album Born for Trouble.
This is a song about a guy who goes home with a 10 out of 10 girl. When he wakes up, he finds she's a 2. Chesney explained to Newsweek: "That's definitely autobiographical. I admit it's not the classiest song I've ever recorded. It's an old Willie Nelson song. This is probably going to be my beer-goggles song. There are girls who are going to listen and say, you know what, I've been there, too. A girl leaving a bar, thinking she's left with Brad Pitt and waking up with me or you." He added: "That was my reality in college a lot. All the guys who have been on the road with me, when I played this song, their jaw dropped."
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.
