Forbes magazine has released their 2015 30 Under 30 in Music list, and it features two of country music's hottest acts: Florida Georgia Line and Kacey Musgraves.

Florida Georgia Line, the duo made up of Brian Kelley and Tyler Hubbard, came in at the top of the list, beating out artists like Meghan Trainor and Iggy Azalea, among others, for the No. 1 spot.

"It’s a huge honor to be named one of the 30 Under 30," Hubbard says. "For us, it’s something that if you’d asked us three years ago, we would've laughed at you.

"We had about negative $30 in our bank account about two years ago. I’m not really exaggerating," he recalls. "So for us, it’s a huge honor, and it’s a testament to our fans, it’s a testament to country radio, it’s a testament to our team and the people that’s believed in us and helped us get here."

Musgraves landed at No. 17 on the list. The songstress, whose freshman 'Same Trailer, Different Park' album was released in 2013, won a 2014 ACM Award for Album of the Year and picked up Best Country Album at the 2014 Grammys. She also received a 2014 CMA Award for Song of the Year, for the album's third single, 'Follow Your Arrow;' the album's debut single, 'Merry Go Round,' earned Best Country Song at the 2014 Grammy Awards.

The songstress spent 2014 touring as a solo artist, with Lady Antebellum and with pop star Katy Perry.

No repeats were allowed on the 30 Under 30 list, which was determined by three industry veterans, eliminating artists like Taylor Swift from the running. Still, plenty of shining stars found a spot on the list, including Big Sean, Ed SheeranSam Smith and more.

Both FGL and Musgraves will undoubtedly have a big 2015. The 'Sun Daze' singers will embark on their 2015 Anything Goes World Tour, which, for the first time, will take them to Sweden, Norway and the UK, with more international dates expected to be added.

“With this tour, it’s our first worldwide tour,” Kelley says. “It’s our first full-year of headlining ... It’s a bigger scale. Bigger venues, more people, more lights, more smoke. More pyro. Maybe some lasers. You never know. We’re still planning. We’re trying to make it big and fun and try to create the best moments that we can. That’s what our shows are all about, moments that you’re never going to forget.”

Musgraves is also adding some dates to her Same Tour, Different Trailer tour this year, keeping her on the road for most of February.
