Florida Georgia Line's hit 'Stay' got a stunning makeover by duo Megan and Liz Mace (known as Megan and Liz), fraternal twin sisters who really know how to sing.

The two gals from Edwardsburg, Mich. are both songwriters, but they obviously know a good song when they hear it, which is why they chose to cover FGL's track.

Their honeyed voices blend effortlessly -- similar to the vocal matchup between Tyler Hubbard and Brian Kelley -- and the song shines when stripped down to acoustic guitar and vocals.

Megan and Liz's rendition of the song is a stark contrast to the country duo's performance of the No. 1 hit at the 2014 ACM Awards. There are no pyrotechnics or flashy videos to pique interest; it's just a fantastic song portrayed in the simplest of ways.

Megan and Liz first broke into the music scene via YouTube after showing off a song titled 'This Note,' which they wrote at the age of 15. Since that first splash, they moved down south to Nashville. In addition to songwriting, they have covered other country artists such as Dan + Shay and Taylor Swift.
