Zac Hanson told the story of the song to AntiMusic
: "Thinking 'Bout Somethin'' originally started as a chorus. We didn't know where it was going to go, and it sat around for a long time. In the past, we've had a lot of ideas that have stuck around and you just keep singing them and singing them. The idea eventually came about of it as a kind of 'done me wrong' soul song. Someone found a similar loop to my drum part and we started rocking out to that, and then I went and jumped on the drums. It really came together once we all settled around the idea of what the song was really about. So much of it is based around the groove and chorus, and the verse was just about the attitude. Once we got the attitude of the song, it was easy."
