David Nail is all grown up, and he hopes that is reflected in his new single, 'Whatever She's Got.' The singer reveals he has finally embraced adulthood, and as a result, released a new tune that shows a different side of him as an artist.

“For whatever reason, it took me a little longer to mature,” Nail tells Country Weekly. “I turned 34 this year and remember turning 33 was an eye-opening experience. I realized that I needed to do a little more of this and a little less of this. I needed to call my friends and family a little more often and make some changes."

He adds, "It was a period of time to figure all that out, and once I did, it took things off my plate that I’d been dealing with for a long time and allowed me to take some creative risks that, two or three years ago, I never would’ve taken.”

The Missouri native, who is working on an album to release later this year, says his new outlook is evident in the songs he is recording, as well as in his personal life.

“I’m at a different place in my life personally and, as a result of that, the music took on a different tone. It tells that story for me,” he notes. “Overall, I’m just a happier person and am more pleasant to be around. I know my friends make a point to tell me that all the time, so it must have been pretty bad!”

The singer's new single has the approval of his most loyal fan -- his wife, Catherine. “It was the first song of mine that I ever saw her dance to. I caught her dancing around the living room,” Nail recalls. “That’s one of a long line of examples that made this such a special song.”

Nail hints that Lee Ann Womack, who appeared on his 2011 album, 'The Sound of a Million Dreams,' will also sing on the new CD. He will spend much of the next few months on the road, performing songs from the new project. See all of his upcoming shows here.
