7. George Jones and Tammy Wynette, 'The Classic Christmas Album'
The title is a misnomer: this 2013 collection is cobbled together from a Jones Christmas album, a Wynette Christmas album, and some holiday duets they recorded while married in the early '70s. But the songs belong together, even if the singers didn't: two of country music's most beautiful voices taking turns singing lonely Christmas laments. Wynette's performance of "White Christmas" is just as melancholy as Jones's "Lonely Christmas Call," making this the perfect album for nursing a holiday heartbreak.
