Carrie Underwood's "Southbound" lyrics make a summer anthem that is pop-country gold.

The country superstar debuted the song live at the 2019 ACM Awards with a summer pool party performance that included an appearance from her Cry Pretty 360 tourmates Maddie & Tae and Runaway June.

Underwood says that this was the last song she wrote for her Cry Pretty album — the "last piece of the puzzle."

"I knew I needed something that was a little more fun," she tells the Tennessean, "Because I felt like we had a lot of kind of serious moments and a lot of emotion that was skewing more not sad, but just a little more serious. I wanted that levity."

Underwood doesn't like going into the studio with an agenda, but she had a plan when she cut "Southbound." The party atmosphere the vibe of the song brings is new for her, but it's set to become the song of summer 2019 — a carefree hit fans and non-fans will jam to out on the water while sipping something cold.

Carrie Underwood's "Southbound" Lyrics:

We got a pontoon boat with a Yamaha / People dressed like they're in Panama / Small town, spring break / Every weekend 'round this place / And there's a bunch of boys trying to catch the eyes / Of all the pretty girls that are walking by / And those redneck margaritas are two for one at that old marina.

Tan lines and gas station cheap stations / They’re coming here from all around.

To get a little southbound, unwound, Tennessee Honey kinda buzz / Then south sounds up loud, summer drippin' off of us / From the river bank to the party cove / Long as it floats, we'll rock the boat / And it's all lookin' up when we get down, yeah / And get a little southbound, southbound / Get a little southbound, southbound.

Bo got a ticket in a no-wake zone / But Katie's the one that should take it slow / 'Cause she's dancin' on the dock and it's only two o'clock / Yeah, the fish ain't bitin' 'cause the party's on / The old men are thinkin' 'bout goin' home / But those redneck margaritas are two for one at that old marina, yeah.

Got the rope swing, swingin' like a chandelier / Little bit of heaven on the water right here / Don't need much, just a couple of beers and you and me / Gotta love this time of year / Getting southbound, southbound.
