Two-plus decades into their marriage, Faith Hill and Tim McGraw are still each other's biggest champions. Case in point: She can't help but dance to his brand-new single, "Way Down."

McGraw dropped his new track on Tuesday (Oct. 1), and the next day, shared a sweet video of his wife on Instagram. Hill and some friends are standing on the floor of an empty arena, a few rows back, as McGraw and his band play "Way Down" — and she is groovin' out!

"Love to see my baby jammin!!" McGraw captioned the short clip.

"Way Down," which comes from a to-be-announced new album by McGraw, is a funky, blues-influenced trip through the south's musical Meccas; its lyrics name-check Alabama, Georgia, Mississippi and more locations. Shy Carter, a pop and country music songwriter who has written previous for McGraw and Hill, as well as for SugarlandKane BrownBilly Currington and others, is featured on the track.

Hill and McGraw will celebrate their 23rd wedding anniversary on Sunday (Oct. 6). The two were married in 1996, after falling in love on a tour earlier that year.
