Contact is hardly the only thing missing from the movie soundtrack. Most of the incidental music is missing (all of the Tune Ups, Voicemails and Christmas Bells.) A number of references to the events taking place on Christmas Eve have been replaced with them taking place on Christmas Day. And perhaps most distressingly literally all mention of Mark's documentary has been removed, down to his meta-narration and speaking in the third person during Goodbye Love. All of this leads me to believe that the movie is a significantly different animal from the stage play. It remains to be seen whether that's a good or bad thing.
