This song is about doing drugs. Asked by Ink 19 if anyone has a drug problem, the band's drummer Morgan Rose said, "I don't think any of us had any real problems. We just dabbled a little bit. So that's written about that."
Rose said this was going to be called "Venetian Blinds" as a joke because according to him, "anybody that does a little too much coke, or speed, knows that you spend the majority of the night sitting in the room looking out the blinds."
"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.
