It could officially qualify for a Best Song Oscar, an award you know they're dying to win someday, especially after having lost to Eminem. The long-term strategy might be to give Paramount the song, but don't have them put it on the soundtrack. If the song gets nominated, it gets more attention. If it wins, so much the better, because people will be more familiar with it and might be inclined to buy the new album (whatever and whenever that'll be). And Paramount knows how to market their stuff for nominations at the end of the year.
Wish it were used in a better movie, but that's another argument.
