I like this sweet duet, by Ireland's Una Healy, with Sam Palladio (who plays Gunnar on TV's 'Nashville').
(The video was promoting the lead single for her debut solo album, "The Waiting Game", released last year. Besides the general Country feel, she also incorporates traditional Irish elements in her vocal, especially around 2.28)
Una was once a member of a UK Pop girl band, the Saturdays, and later had a background in various reality television shows, becoming first a mentor and later a judge on "the Voice of Ireland". Since committing to Country, she opened for Reba McEntire at C2C, and recorded a cover of Randy Travis's "For Ever and Ever Amen" for a CMA project. You can see that cover here:
