Movie soundtracks tend to bring out the very best in pop stars.
For certain artists, the best song they'll ever write in their whole career will be for a movie.
It might be because movies are larger than life, and the songwriter ends up aiming for a similarly epic vibe.
It's probably also because they are presented with a completed narrative and they can extract the juice from it for their own purposes.
The only Eminem song I can stand to listen to is Lose Yourself, which was written for his flick 8 Mile.
Paramore's Decode, written specifically for Twilight, is by far their most exciting work.
I could go on but you probably get the point.
Then there are those songs - some by one-hit wonders - which are hits because of the movies.
Eye Of The Tiger is Survivor's only song to have actually survived over the years.
That said, the soundtrack for The Hunger Games: Catching Fire is a treasure trove.
Take, for example, Coldplay's new song Atlas for the movie, which opens here Thursday.
