I think of today's "Top 40"/pop music as a fad. Although I have no way of knowing, I don’t think “Top 40” music will be listened to 30 years from now or will have any lasting impact.
Will the people who listen to this music today still listen to it tomorrow? Probably.
I don’t see any "top 40" hall of fame being built in the future.
In the future, oldies stations will still play the same songs they play today.
When a song is played on "new hit stations" it is out of circulation in a few months. Where does the song go?
New music genres will be created and people will either hate or like them because TRL plays the music videos.
hmmmmmmmm......
