I know this request doesn't involve lyrics (sorry if that is bad), but I don't know where else to go to identify this piano piece!
This piece is one a friend taught me to play on the piano, but he didn't know the name. All he knew was that it was a song that was written for/dedicated to the year 2000 for the millennium. He also said there was a music video of it where there was a man dressed in white playing it on a white piano outside in a snowy area. While the man in the video was good enough to play it by himself, many people play it as a duet/four-hand piece.
After he taught it to me, we recorded the duet. Here it is for you all to identify! (Note: It's not the best recording! He had just taught it to me and we only had practiced a few times before recording it with the built-in mic on my laptop!)
