Soundtracks occasionally define certain moments in film, some of them so perfectly becoming a part of the movie that they melt in the backgroud, but not in a bad way. We're talking here about the songs used for soundtracks and their compilations, we're saving best original music for another day. Here are eleven of the most perfect movie soundtracks.

1. Donnie Darko

From the amazing Duran Duran, Notorious to the brilliant Mad World, Darko is certainly top of the favourite soundtrack lists.

2. Romeo and Juliet

Mundy's To You I Bestow, Radiohead's Talk Show Host and #1 Crush from Garbage are just some of the gems on this soundtrack.

3. Pulp Fiction

It was a teenage wedding and the old folks wished them well...

A cult favourite, this soundtrack is just a masterpiece. Meatloaf!

That final scene with the Pixies, just a masterpiece.
