So what won?

I just love the song. And despite it coming from a forgotten movie, it has stood the test of time. Besides, most people associate it with Ghost...so, yeah.

Analysis
This was a pretty good year. I liked all of the songs for the most part. And I have no problem with "Love is..." winning. It's a very good song and probably deserved to win. Good year.
