9. Pistol Annies, 'Annie Up'
Opening with an a capella declaration of purpose underscored by finger snaps ("I Feel A Sin Coming On"), this badass all-woman version of The Highwaymen proved their debut was more than just a one-off. With two of the genre's most accomplished singer-songwriters (Miranda Lambert and Ashley Monroe) and an up-and-comer (Angeleena Presley), they're supergroup proof of the woman-led sea change in mainstream country. Sharpest moment: "Being Pretty Ain't Pretty," a sufferers anthem for fashion victims and those who love them.
