If nothing else from her, then definitely "Mine" and "Sparks Fly".
"Change". Taylor's account of her and her band's struggle to be noticed- with a note of confident triumph. Taylor's dad convinced her that the song could be applied to other people and events- and it's a fitting closer to "Fearless". "...and we'll sing hallelujah."
"Long Live". The melody came to Taylor while she was touring for "Fearless" hearing the screaming crowds.
