16. "Ours" (2010)
Like so many of her songs, "Ours" sounds like it could be channeling the 16-blue mojo of the Replacements' punk-rock bard Paul Westerberg. (Melodically, it evokes "When It Began," though it feels more like "I Will Dare.") Especially the best line, which is possibly the best-est "best line" on this list, and which I sing to myself a mere dozen times a day.
Best line: "Don't you worry your pretty little mind/People throw rocks at things that shine."
