"Southbound" is a song co-written and recorded by American singer Carrie Underwood, and released as the third single from her sixth studio album, Cry Pretty. The single had an official release day of April 29, 2019. The song was written by Underwood, David Garcia and Josh Miller.
“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." 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." “Southbound” was one of the final songs written for the album.
