Author's Saving Throw: After the positive reception of "Dirt" and "Confession", it seems that the duo has decided to emphasize ballads more strongly on Dig Your Roots.
Critical Dissonance: The band is quite polarizing in the country music fan community (especially after the Nelly remix of "Cruise"), due to their hard rock influence and reliance on party jams, but they're one of the hottest selling country artists. Some have even considered them the Nickelback of country (and in fact, they're produced by former Nickelback producer Joey Moi).
"Cruise" in particular deserves special mention. Even before the remix, it was pretty polarizing for its rap influences, but this didn't stop it from hitting #1 on the country charts and selling over 2 million copies. After the Nelly remix, the song and the duo themselves became even more polarizing, with some deriding the band for "selling out." Despite this, the remix helped the song sell even more and reached #4 on the Hot 100. In the end, "Cruise" has sold over 6 million copies, making it one of the best selling country songs of all time.
Covered Up: "Stay" was originally recorded by Black Stone Cherry.
Snark Bait: Due to their status as being the faces of the maligned "bro-country" movement, they tend to be the butt of jokes involving modern country and their attachment to beer, girls in bikinis, and trucks.
Win Back the Crowd: Apparently the derision for being the Trope Makers and (along with Luke Bryan) the Trope Codifiers of "bro-country" has resonated with FGL, as their second album is led off by "Dirt", which is noticeably more substantial than nearly anything on their first album.
