Sound track to my life (draft version)

This is a meme that does the rounds every so often; most recent incarnation from rysmiel. The idea is that you a dozen or so songs that would form the sound-track to (a film of) your life.

I've gone for songs that were playing at significant moments, rather than songs I necessarily think are out of this world wonderful. I'm also finding this surprisingly hard, so I'm not sure I've picked the most appropriate ones. I've tried this meme or variants on it several times, and this is the first list I've been at least vaguely content with.
