I like this song. Especially the drums and piano.
"Inspiration comes from the most unfamiliar places" - very good line.
"What will be, will just be" - also a good line, and probably true.

I like how this song captures the early phase of a relationship ("Back to the place where we went slow").
"Mystery" in this song can mean lots of things -- a person's vulnerabilities, their naked truth, their naked body. When you fall for someone, you want to see everything about the person. You want to be with the person, totally. If you stay together long enough, you grow together and hopefully look back to your early days as a couple with happy memories. In times of trouble, it might even help to look back to when you first met and believed you were at your best.
