Cover art for Casualty lyrics by Snake River Conspiracy

I would update the lyrics in the comment section, but it looks weird. Great vocals from Tobey, please check out the duo Mojave Phone Booth if you haven't already. My interpretation of this track is it's a reflection on a past relationship that has left them feeling like a casualty. They seem to be lamenting their loss and the power that the other person holds over them. The repetition of the phrase "casualty of you" emphasizes the idea that the person feels like a victim by the other person's actions, but then the phrase "you turn me on" hints at a physical attraction or connection that they still feel towards the other person, despite the hurt they have experienced. It's both conflicting feelings of desire and pain.
