Taylor Swift's latest song 'Welcome to New York' -- the first track off her upcoming album '1989' -- is slated to be released via iTunes tomorrow (Oct. 21). But considering it is already Oct. 21 in Russia, the song has already been released and naturally found its way online -- and the fan reactions all over Twitter (everyone is either screaming or crying... sometimes both) are priceless. Check out some of our favorites -- rife with excessive caps lock -- below!

You won't be able to listen to the full song here -- we're waiting until it hits iTunes here in the U.S. to get a copy for ourselves -- but judging from the above tweets it sure sounds like fans think it's a hit! Listen to a short preview clip of the super synthy, '80s inspired track below, and be sure to get the song when it officially drops on iTunes in your country.
