I'd have to say Let Down. Though maybe not may favorite song on the album, the lyrics actually hit me every time i hear it.
When I really think about it - the ideas of moving on from events and people; the difficulty of not falling into a pattern, or following a path that may be familiar, but also damaging - the song makes me think of the shit I've dealt with, the mistakes I've made, but also how I've matured, and grown, developing into, hopefully (), a better, stronger person.
Sometimes you can see something developing, you can see how things are gonna turn out, and it's still a struggle to change, especially yourself.
