Why not? Familiarity and association with positive emotions surely has a strong effect on our music tastes. It's why people often gravitate to the music of those around them they identify with.

The movie Titanic single-handedly turned me into a classical music aficionado.

I've sought out the songs from a lot of shows and movies over the years, so can only imagine others would do the same. Of course, a lot of the time, it's a single song by a given artist that I like, where most of the rest I could care less for.

All I can say, is give it a watch. Funny and heartfelt writing, regularly featuring a song from a contemporary folk artist. I think Zach Braff got much of the credit, and took some of that sensibility to the big screen with Garden State.
