This is a track from American Contemporary Christian singer-songwriter Sara Groves' album, The Other Side Of Something.
The song was inspired by a huge argument that Sara had with her husband, Troy. She told Christianity Today magazine: "It's about a couple in bed with their backs to each other after a massive fight—one of our biggest. And I wrote that 10 minutes after the fight. I was so angry, but he was leaving for Africa the next day, so I knew that reconciliation had to happen. So I went and wrote 'Roll to the Middle' freshly out of that place. The album was already done, but Troy insisted that song be on the album."
