Growing up some of my favorite CDs were movie soundtracks. The good ones always had a collection of great songs that perfectly encapsulated the mood of the film. Some were a handpicked selection of Top 40 hits ("Saturday Night Fever," "The Big Chill") while others were eclectic mixes of songs I had never heard before ("Trainspotting," "Natural Born Killers"). The best soundtracks gave a great variety of music and were huge sellers for record companies and studios alike.
