Taylor Swift seems to air dirty laundry via songwriting -- specifically her relationship with fellow musician John Mayer -- on her perfectly titled new song 'Dear John' from the current blockbuster album 'Speak Now.'

The sad, lilting acoustic guitars and stately tempo of the track belies the anger and judgement spilled out lyrically throughout 'Dear John.'  In successive verses, Swift very plainly accuses a former lover of being moody, manipulative and generally far too cavalier with the affections of a 19-year-old:

"My mother accused me of losing my mind / But I swore I was fine / You paint me a blue sky / And go back and turn it to rain / And I lived in your chess game / But you changed the rules every day."

Assuming the gossip is true, giving a talented songwriter like Swift the chance to write a "Dear John" letter to a guy actually named John is like leaving a slow curveball hanging over the plate for Adrian Gonzalez. You know they're going to hit it out of the park, and Swift does just that on the chorus:

"Dear John / I see it all now that you're gone / Don't you think I was too young to be messed with? / The girl in the dress / Cried the whole way home / I should have known."

Now, let's all remember, Swift has never publicly stated this song was about Mayer, and even if it is, all we're getting is one person's side of the story. (Still, it's kinda fun to think about, right?)
