Not the song, the actual line "Feel Good Drag"
Also what the heck did Anberlin mean by "Discourse your saving song?" This song is so confusing
The lead singer, Stephen Christian, told Artist Direct the story behind this song: "The whole underlying theme is talking about going into a relationship that you know is destined to fail. It talks about lies and crush that allow you to go into that relationship but in the back of your head. It's kind of like cheating, like she's dating someone else or you're naïve to how something works. With naivety you just get sucked in. That's the song. There's that underlying story—just being a nice character walking into a relationship."
But why does it matter what the meaning of the song is? It's a good song and that's all that matters.
