What's unfortunate (I'm not arguing it's unnecessary, that's another discussion) is that the music on terrestrial radio is selected based on stats, not on taste.
When music is chosen for a movie, there's often no discernible correlation between the songs. When they were written, who performed them, what demo they "resonate with" and all the other stuff that radio programmers pour all over is all over the place. They're GOOD SONGS -- that's the bottom line -- and they fit the mood of the action that's on the screen at the time. That's called "creativity" and it doesn't exist anymore on commercial radio. I'm not sure it exists in the online world of Pandora and Spotify either.
Creativity is prone to failure, but when it succeeds it succeeds big time and moves things forward. Programming by numbers maintains the status quo, but stagnation sets in followed by decline. But it's always safest in the short term.
