Musik is created twice. Once in the mind of a composit or a songwriter. An a second time in the mind of the listener. Except there is not one listener.
Whenever a song, or any piece of music for that matter, is listened it is reevaluate by the listener. Most clubmusic does not change that much.

But then there are songs that tell more complex stories. Or songs that try to capture a complex spectrum of emotions.
These songs can create different affects on different people. Or even on one person in different times.
