YMMV / Jason Isbell

• Covered Up: The Zac Brown Band's cover of "Dress Blues" didn't get a ton of airtime, but a lot of country fans are more familiar with that version. Similarly, Morgan Wallen covered up, appropriately enough, "Cover Me Up".
• Memetic Mutation: Even if you don't follow alt-country music, you may still have heard of him, via the "30 to 50 feral hogs" meme. (To save you a click: he wasn't the one making that argument.)
