I think they did. Florida Georgia Line just released their new song, "I Love My Country" and right at the end of the song, you can hear a "Yee Yee" battle cry from Tyler Hubbard, 1/2 of the duo along with Brian Kelley.
I love FGL but I REALLY love their party anthems. This is a good one and not just cause there's a good ole "Yee Yee" in it.
This song reminds us of one of those songs you'd jam on a late summer night in the backwoods while you're crackin' cold ones with your buddies.
