Covered Up: Subverted with "Chicken Fried". The band first recorded it during its independent days, and later gave the song to The Lost Trailers who released it as a single. Then Zac changed his mind and asked The Lost Trailers' label to pull their version.
Also, "Colder Weather". Despite being a little vague and open-ended (on purpose), it'll really get to you with its story of a man and woman who are separated by colder weather.
