Songfacts®:

• "Sweet Thing" was written by Urban together with Monty Powell and co-produced with longtime Urban producer Dann Huff.
• This song is a look back at the first pangs of new love. Urban, who is now married to the actress Nicole Kidman, commented with a grin in Australia's The Daily Telegraph: "Oh I can relate to that guy. I like that sort of romance and that feeling of always trying to be worthy.''
• Urban recorded this song at Castle Recording Studios in Franklin, Tennessee.
• This was Urban's 10th #1 on the Hot Country Songs chart.
• Urban discussed this song on the country music website Roughstock: "I have a '69 Mustang. I drove it to a writing session with Monty Powell that day. This song came very quickly: about early romance and courting. 'Courting' is such a beautiful term. It keeps everything vibrant and full of life. Monty had this great lyric and we got to the last verse, where we needed a car reference, so he wrote that bit about the Mustang because my car was sitting in his driveway."
• This song's reference to a "lovestruck Romeo" was taken by Urban from the lyrics of the Dire Straits song "Romeo And Juliet."
• Monty Powell told The Boot the story of the song: "We spent the morning working on a song that, frankly, really wasn't great. We really tried hard to have a breakthrough on it, and it wasn't happening. We were both kinda tired and grumpy, and we were hungry, so we just said, 'Let's go get some lunch."
  
  "[Keith] had shown up at the house in his brand-new Mustang that his wife, Nicole Kidman, had given him as a gift. I was like, "This car is spectacular; let's go in it." We went driving around and got some lunch, and then we drove [around] for a little bit because we were having such a good time."
  
  "We came back to the house, and instead of even revisiting the song we had started that morning, Keith just started playing this riff on the guitar that is now the 'Sweet Thing' riff at the top. I just started singing this lyric about the car and the first date he had with Nicole. The song just started flowing, so I really have to thank the car for giving us the inspiration for this one."
