Best to be the best you that you can be

XTC's "Wrapped In Grey" works just as well for drifting off to sleep as it does for waking up.  If you feel like hibernating, you can concentrate on the deliberately grey-sounding, melancholy instrumentation in the intro.  If you're waking up, you can concentrate on the lyrics about remembering to do the things that make you unique instead of sleepwalking through the day.
