And for Evans, whose seventh studio album Slow Me Down was released earlier this week, she found that "great" song in the record's haunting title track. "That song became the centerpiece of the whole album because it was my favorite song," Evans says of "Slow Me Down."

"There's just something about it," she continued. "It's sad, but it's also kind of mysterious. I just love how the girl in the song is so completely vulnerable because she's saying, 'I love you and I want to be with you, but I'm trying to tell you that these things need to change, and if they don't, then I've got to leave. I've got to have that much self respect, and I have to walk away from the situation, but I hope that you won't be able to live without me and that you'll stop me from leaving.'"

In addition to "Slow Me Down," the album also includes poignant duets with Vince Gill, Isaac Slade of The Fray and a cover of Gavin DeGraw's "Not Over You," which features DeGraw on harmonies.
