One is a powerhouse vocalist who's influenced a generation (or more) of country singers. The other is a powerhouse vocalist still looking for her first big hit song. Two of country music's finest singers will face off in this contest to decide the best in the genre. This week, fans will have to decide between Reba McEntire and Mickey Guyton.

McEntire is as dynamic a singer as you'll find. Her storytelling is unmatched, but she's much more than a humble troubadour. When the famous redhead sings, she soars and fans take a wild, twisting and turning emotional ride. Few have accomplished as much as she has during her lengthy country career, but is she the best female vocalist of 2016?

Guyton's fans could argue that based on pure vocal power, she's the best. The "Better Than You Left Me" singer injects an amount of emotion that's rare into her storytelling as well, and the sheer strength of her vocals hit like a storm. She's poised for a big career in country music, but she'll need total fan support to knock this legend out of Round 1.

Vote once every hour until this Round 1 poll closes on March 13, 2016 at 11:59PM ET. The winner will move on to face either Cassadee Pope or Jennifer Nettles in a Round 2 matchup. At the end of three weeks, the top male vocalist will square off against the fan-decided top female vocalist to decided country’s top vocalist of 2016.
