Not sure which version is the "first" version of the song, but from the comments on the second one listed:
First "You" : Beginning of a relationship
2nd " You" : The end of a relationship, looking back ,reminiscing...
I agree. I was sent this song (1st version) by an ex-girlfriend a long time ago, loved it, played it constantly. Fast forward some time, I'm in the car with that girlfriend and this song comes on. I turned it up thinking she'd recognize it, and she had no idea what I was talking about; she liked the song, but had never heard it before. I told her she sent it to me, and she pulled up on her phone and found what she sent me which was the 2nd version, a version I'd never heard before. Apparently, something was lost in the translation, and her link directed me to the alternate version, but when I hear either one today, there's a little heartache there. Two versions of the same song that reminded of us of each other, and neither of us was hearing the same music.
