Cover art for Clevermind lyrics by Poets Of The Fall

I agree that it's about a lost relationship. The person keeps thinking of what they could have done to fix it ("words that might have warmed December", "forever now unsaid"). They think they'd have "earned a chance or few" but there's nothing more they can do. Their inner voice is trying to reason "Look the leaves are dead" (this and "December" refer to winter - the coldness that remains) and "I gotta throw my hands up / I can't go on if I can't stop" - it's better to admit it's over or they cannot go on to new beginnings.

I do wonder why the title "Clevermind". Probably referring to how the person is wiser now ("learned a thing or two") but "never mind" - because it's too late.

A pretty accurate description of my own breakup (except it was November :P). And I'm glad the "winter" is over now ;)
