This is the first track off my newest album, Embers. It's about the imperfections that both manifest and are revealed over time, kind of like when a person buys a used car. As far as metaphors go, it's pretty straightforward.
You can stream it on Spotify here. The chorus on this one is particularly fun to sing: "Some city, mostly highway..." It's hard not to smile on that line. If you want to sing along, you can find the lyrics here.
