Keith Urban and Monty Powell had been writing together for 15 years and celebrated several big hits together before "Sweet Thing" came along. The song was released in November of 2008, as the first single from Urban's 2009 album, Defying Gravity. It debuted at No. 30 on the Billboard Hot Country Songs chart and hit No. 1 in March of 2009; it also won a Grammy, for Best Male Country Vocal Performance, in 2010. However, if it wasn't for a Mustang, the song may never have been written.
