"What never grows old? The burning desire of youth to reinvent the world" — so says Forbes, who for seven years now has compiled an annual list of impressive, accomplished, and just plain hustlin' individuals under the age of 30. The list is customized for a variety of different categories, including music, and it's that very list that two country artists showed up on.

Maren Morris, 27, was noted by Forbes for her 2015 major label debut, which hit the top of Billboard's country albums chart and made it at No. 5 on the all-genre Billboard 200. Also lauded was her Grammy nomination for Best New Artist at this year's ceremony (she lost to Chance the Rapper).

Thomas Rhett, also 27, was duly noted for his money-making skills — a quarter million dollars per night on the road — as well as the performance of his third album, Life Changes, which debuted in September at the top of the Billboard 200 (it was the first country album to do so this year).

Morris and Rhett join such standouts as Paramore's Hayley Williams, Cardi B, Jackie Evancho, Joe Jonas, Bebe Rexha, and Khalid on the outlet's music class of 2018. Other categories in the feature spanned everything from sports to science to education.

The two artists collaborated on Rhett's "Craving You," which hit No. 1 on both the Billboard Country Airplay and Mediabase charts.
