This is a track from Erase Me, Underoath's first album of original material since 2010's Ø. The record finds the Florida post-hardcore outfit shedding their faith-filled worldview replacing them with lead vocalist Spencer Chamberlain's lyrics about his drug dependency. He told Kerrang.
"It's a breakup record, but not about a girl: this is about the end of my chemical dependency. It's about my breakup with drugs, and the struggle of me realising that I had a problem. I was in my final years of using while writing the album, and by the time I finished writing it, I was clean."
"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.
