Uh oh! Looks like some people just couldn't wait until October 22 to hear Taylor's highly anticipated fourth studio album Red. While it has been reported that the entire album has leaked onto the internet, the song Everything Has Changed, a duet with British singer Ed Sheeran, has spread the fastest. The two wrote the song together and the track has the sound like a friendly acoustic jam session which contrasts with many of Swift's highly polished singles that have already been released off the album. The duet does not disappoint and many fans have been quick to voice their approval of the beautiful, if not expected sound of the first Red collaboration.
