We tend to like the music that was playing when we were most impressionable and new experiences were a regular occurrence... who can forget that song that was playing when you met your first love, had your first drink, drove your first car, smoked your first joint, went to your first gig..?
Important events indeed and the soundtrack to them is burnt into our minds and have special significance.
I'm sure it is no different for today's teenagers.

This.
Music and movies are as important to teens & early twenties as they were in my time (90's) and every decade before that.
The first half of the previous century these influences came more from religious, political and class of the neighbourhood one grew up in.
After WW2 media and technology became rapidly available to more and more people, so they were affected by influences beyond their normal surroundings. Pop culture emerged as a new way to define oneself, and has only developed and professionalised since.
Errmm where was I going with this again?
