The new songs on Faith Hill's Deep Tracks album aren’t really new. They've just never been released until now.

But the last three recordings on the the compilation sound modern and fresh, regardless of when she recorded them.

Even “Why,” which Hill said she cut 12 years ago.

“I recorded ‘Why’ for the Fireflies album in 2004," Hill shared on social media. "When it didn’t make the final cut for the album, Dann Huff, who produced the track, ended up recording it with Rascal Flatts, who released it in 2009. It is a very poignant song and still resonates today."

The piano ballad, written by Rob Mathes and Allen Shamblin, is her husband Tim McGraw’s favorite song that she's recorded.

And “Come to Jesus” is the closest Hill ever got to making her mother’s dreams of a gospel album come true.

“Three weeks ago today my mom passed away. Mom often asked if I would ever get around to recording a gospel album. That's all she wanted to hear me sing. I'm thankful that she was able to hear this song before she took a seat on the glory train,” Hill wrote, dedicating "Come to Jesus" to her mother Edna Perry.

Of the other unreleased one, “Boy,” Hill wrote simply that it is one of her favorites “because it reminds me of my man. Hope you like it, too.”

She also shared some heartfelt words for the people at her label, Warner Bros Nashville, where she has been since signing in the early '90s and releasing her debut album Take Me as I Am. Among them are former A&R executive Martha Sharpe ("the powerhouse who signed me") and former label head Jim Ed Norman ("a true gem in our industry").

"I would never have been able to be the artist that I have become at any other place on this planet," she wrote. "It was Jim Ed’s idea to release 'Breathe' as the first single from the Breathe album.

"Even I, the risk taker, the rebel without walls, was nervous about that song being chosen as the first single. That decision changed the trajectory of my career. You allowed me to explore my musical growth as an artist without hesitation. I literally grew up as a woman and an artist in the protective arms of so many at Warner Bros. You never once questioned the fact that my family came first, and I will be forever grateful that I was lucky enough to be in such an environment."
