In our interview with Brad Smith
, he told us the story behind this song: "I moved out to LA with this girl who was really into the new age movement, the Age of Aquarius or whatever that stuff is, with like crystals and tie dyes and hemp bracelets on the beach - just a free spirit type of girl. She came very much from that type of spirituality, and she would always tell me, 'It's like we're soul mates. We're soul mates, we're going to be together forever,' and all kind of stuff like that. I didn't really buy it. I did feel a connection with her and I was in love with her at one point, but I think she was just too crazy for me. And 'Soul One' is a little bit like that. The bridge gives some kind of resolution, it's like, 'I thought she was, I thought she was my soul one.' We broke up and we went on our separate roads. So that's where that song came from, from me.
But looking back on it, I think she was right. I think you're soul mates with a lot of people. Because I reflect back on that first relationship even in my current marriage and how much I learned from that first relationship and things like that. So in a weird way she's still with me. So I guess we were soul ones.
So 'Soul One' kind of was inspired by an ex girlfriend who was into the new age philosophy."
