Unbreakable Heart

Written by Benmont Tench, who is the keyboard player in Tom Petty and the Heartbreakers, this song finds Carter telling a man that God can make anything out of nothing, but God has never made an unbreakable heart and probably never will. She wants him to know that he has to be careful with her because God didn't make her with an unbreakable heart.

Benmont Tench wrote this song when he was going through a divorce. He and Carter are good friends, and the day after he wrote the song, he called her and asked if she wanted to record it. Tench had been working with Carter on her Little Love Letters album, so he brought her the song and they recorded it that day. "I just got my hands on it before anybody else did," Carter explained in her Songfacts interview. "It's a brilliant song and when he played it to me on the guitar and sang it to me, I was just blown away."

"Unbreakable Heart" was a phrase Benmont Tench saw on a billboard. He and a friend agreed to each write a song with that title; what started out as exercise became a very personal song. In our interview with Tench, he said: "It just so happened that it really connected with me in an emotional way. I think I was thinking of 'True Love Ways' when I wrote that song but I wasn't consciously going, I'm going to write a song like that. I think those were just the spirits in the air."
