34. Neko Case, 'The Worse Things Get, the Harder I Fight, the Harder I Fight, the More I Love You'
The country-rock firecracker's sixth LP is full of bold arrangements and hot guitars (courtesy of My Morning Jacket, among others). It's also a tour de force of intense, big-chorused songwriting. In other words, plenty more than just a big voice. But, damn: That's one knee-bucklingly magnificent voice.
