I would say the version in the actual movie running over the credits is a seperate version, almost a hybrid of the "Single Version" and this new "Alternate Version", it doesn't fade out, and has the extra lyrics.
I have :
4 distinct "Official" Versions
Ordinary Love (Soundtrack Version - Edit / Single Version)
Ordinary Love (Paul Epworth Version) - Alternate Lyrics
Ordinary Love (Soundtrack Version - Full)
Ordinary Love (Alternate Version - Interscope Promo)
2 "Unofficial" Mixes
Ordinary Love (Q-Music Mandela Edit)
Ordinary Love (Devin Wild And Sub Zero Project Bootleg)
2 "Live Performances"
Ordinary Love (Live, New York, February 17, 2014)
Ordinary Love (Live, Los Angeles, March 2, 2014)
