Thomas Rhett’s love song for his better half has been climbing the charts over the last several weeks, and it’s officially earned Gold certification from the RIAA, meaning it has sold more than 500,000 digital copies.

Rhett wrote the tune hoping one day it "becomes a lot of people’s wedding songs,” he says. "It’s a super, super, super love song. I wrote it about my wife.”

The song appears on his most recent album, Tangled Up, and the artist says his wife, Lauren, actually had a hand in shaping the tune. He tells Taste of Country she’d been asking for a love song, and that her stamp of approval is very important to him for all of his music.

“If she doesn’t think something is cool, I have to like really think it’s cool to still do it,” Rhett says.

“I just think this song shows how me and Lauren love each other, and I hope this song is an encouragement to other married couples or people that are dating,” he adds of "Die a Happy Man."

The artist has said Tangled Up is “100 percent Thomas Rhett,” but that means it’s a little left of center for country music — in a good way. His R&B influences and up-tempo dance beats shine through on the record, placing him in a category all his own. Its first single, “Crash and Burn,” hit No. 1 earlier this fall.

Rhett is currently on the CMT Suits and Boots tour with Brett Eldredge and Danielle Bradbery. Rhett also recently performed “Crash and Burn” alongside pop-rockers Fall Out Boy at the 2015 CMA Awards Nov. 4, where he was nominated for New Artist of the Year.
