This song is a collaboration with Wild Belle, who are an Illinois pop-rock band comprised of siblings Elliot and Natalie Bergman. The duo are best known for their single "Keep You," which featured in the movie Pitch Perfect.
The vocalist here is Natalie Bergman who sings of a love for a guy who is a "dreamer at heart." She acknowledges on the face of it a relationship is unlikely but still hopes they can be together someday.
It really was so easy for Linda Ronstadt to score a hit with her Buddy Holly cover of "It's So Easy." She would sometimes change the lyric to: "It's so easy to have a hit, all you have to do is recycle it."
