Thomas Rhett has picked "Life Changes" as the fourth single from his third studio album, also called  Life Changes.

The title track is chasing the success of three previous chart-toppers in "Craving You," "Marry Me" and "Unforgettable," and this three-minute autobiography will also stand the test of time. "Life Changes" shows the singer's evolution from college student, to country star, to husband and now father of two.

“It covers my college years, marrying Lauren, becoming a dad and the evolution of my music career," Rhett explains. "It’s definitely the most personal song I’ve ever written, but we all go through a lot in life whatever the story is, so I think the sentiment is something a lot of people can relate to."

"Life Changes" just feels good. Rhett reminisces about a pretty average college experience before he became a global star. "Majoring in Undecided / Notebook full of bad songs I was writing / Never dreamed anybody else would like them / Now they're sitting on a Walmart shelf," he sings in the song's first verse.

With slick production and Rhett's slowed talking/singing style, it's a new approach for the singer. Keyboard and percussion accompaniment further accent the song as Rhett notes how his life has evolved and that he wouldn't change a thing.

"You make your plans and you hear God laughing / Life changes, and I wouldn't change it for the world," he sings in the chorus.

Did you know? "Life Changes" was written by Thomas Rhett and his father, Rhett Akins, along with Jesse Frasure and Ashley Gorley. This isn't the first time the father and son have shared writing credit on one of Rhett's singles — they also co-wrote "Star of the Show."

Thomas Rhett's "Life Changes" Lyrics:

Waking up in my college dorm / Yeah, my life, it was pretty normal / Looking for a date to the spring formal / Wasn't worried 'bout nothing else, no / Majoring in Undecided / Notebook full of bad songs I was writing / Never dreamed anybody else would like them / Now they're sitting on a Walmart shelf

Chorus:

Ain't it funny how life changes / You wake up, ain't nothing the same and life changes / You can't stop it, just hop on the train, and / You never know what's gonna happen / You make your plans and you hear God laughing / Life changes, and I wouldn't change it for the world, the world, oh no / And I wouldn't change it for the world, the world, oh no

I bought a ring and she said, "I do" / But everybody else said, "Man, you're twenty-two / Whatcha trying to prove? Hey, why don't you wait?" / 'Cause I've been waiting on her since the second grade, yeah / And now she got her own set of fans / Got a blue check mark by her Instagram / And I wrote a little song about holding her hand / And now everybody wanna die happy, man

Chorus

I remember the day I told my Daddy and Mama / "You're gonna have a grandkid, yep / From Uganda, that's right, we're adopting / And she is the cutest little girl that you've ever seen" / Well I was wrapping my head around being a dad / A big wrench got thrown in the plans we thought we had
Now Lauren's showing, got one on the way / Yeah that's two under two, hey, what can I say?

Chorus
