Alyssa penned this song in her bedroom after breaking up with her first proper boyfriend. She told 4music: "It's really embarrassing, but it's one of my favorite songs on the album, and it means a lot to me. And it shows people who I am - not only as an artist, but a person. And I think that would connect me to people."
Alyssa told 4Music that not only has her former boyfriend heard the song, "but he knows that the entire album is about him. And he tried to come back."
"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.
