Cover art for This Is War lyrics by Ingrid Michaelson

This definitely sounds like a follow-up to "Soldier" from the Everybody album. A simple song about unrequited love that the singer won't give up on, with vivid imagery of battle. Ingrid Michaelson's gift is her knack for pretty and quirky songs about how love often sucks, and how many different ways she's found to express that.
