At the moment, I'm inclined to vote for "Time", for the following reasons:
1) I keep playing DSOTM, lately, and that song has been socking me in the gut in all sorts of ways...including but not limited to the sudden realization of just how much time has passed, and how swiftly it goes...(You youngsters out there will find out what I mean, someday.)
2) It seems to me that the solo in this song encapsulates absolutely everything the song is about - the tone ranges from mournful to raging to resigned to resolute within such a short span of time. It really is beyond words, for me.
Of course, ask me in a few weeks, and I'll give you an entirely different answer.
Cheers!
