This song originally appeared on the compilation album Golden as an outtake from Failure's 1992 Comfort record. It was later re-recorded with a new bridge for The Heart Is a Monster.
The Heart Is a Monster is also a lyric on the retooled version of this song. Multi-instumentalist Greg Edwards explained to About.com: "I had that title when we were kicking around the idea of naming the album. And then Kellii and Ken both really liked it. Soon after we decided that would be the name of the record we were working on that bridge for 'Petting the Carpet'. I was writing lyrics and decided spur of the moment to work that title into the song."
"Thinking About You" was the ninth track from Calvin Harris' 18 Months album to enter the UK singles Top 10. No other artist has obtained so many hits from one LP - Michael Jackson was the previous record holder with seven Top 10 tunes from both his Bad and Dangerous sets.
