Southbound (Carrie Underwood song)

“Southbound” was written by Underwood, co-producer David Garcia and Josh Miller. Underwood said of the writing process, "I was like, 'This sounds like fun, I think. We can do something fun with this.' But then you realize how tricky for some reason it is to be a woman and write kind of a drinking party boat song. You wouldn’t think it would be any different, but for some reason, I feel like a guy could get away with saying this line that we just threw out there, but I can’t for some reason."^[2] When talking about particular characters in the song, she added, "I used Katie in the song as an example. So, Katie, we wanted to make her have a little too much fun, but for every line we came out with, it was like, 'Well, we don’t want it to be sad.' We still had to make Katie have a little respect but wanted to just get it out there that some people were having too much fun. It surprisingly took us a while to write it but by the end of it, it was like, 'Well, this is a lot of fun,'" she added. "I feel like everybody kind of gravitated towards that one when we were all done with it."^[3] “Southbound” was one of the final songs written for the album.^[4]

Entertainment Weekly gave the song favorable reception in their review of the album, writing, "One of Cry Pretty's strangest surprises is a Florida Georgia Line-style party song called 'Southbound' that finds her singing about tan lines and 'redneck margaritas.' It's probably the most casual Underwood's ever been, and, sung by a male artist, it would have felt almost impossibly unoriginal. Recorded by a woman who doesn’t exactly make pontoon day drinking a part of her personal brand, it's pleasingly contrarian: perhaps it's Underwood trying to reclaim a style of music that's been co-opted and ridden high on the charts by the genre's leading men."^[5] Sounds Like Nashville similarly praised the song, highlighting its "propulsive rhythm, sunny guitar riffs and breezy organ accents", also noting that it was "the first time in recent years that the Oklahoma native has offered up such a carefree track, and its good-time lyrics are all about pontoon-boat weekends, two-for-one redneck margaritas, tan lines and cheap sunglasses."^[6]

Consequence of Sound gave a less favorable review of the song in their review of the album, writing that it was "a bit of fluffy party music high on southern pride."^[7]
