I wasn't aware we were discussing songs played on the radio. I was just discussing music in general. We all know, courtesy of K.M. and DE, that music radio is totally dependent upon the agency biz so old music, by definition, will not advertise well so it isn't played. Even so, there are a smattering of stations that still play Oldies and Classic Hits and I am still amazed, from time to time, when I run across 20 and 30-somethings that not only love the music but know the lyrics as well. I attended a wedding of two 30-year olds two weeks ago and most of their reception music was from the 50's, 60's and 70's. Ad agencies doing TV commercials appear to also like them as they are frequently used there as well.
As I have mentioned in previous posts, Standards don't stand up well because a large part were WWII-related and don't play well now for obvious reasons. Others, such as Christmas Standards are timeless and are played relentlessly during the season. Dance Standards still draw well in plays and stage shows - most of which are performed by college and high school-aged performers.
Suffice to say I am not the lone voice hollering in the wilderness. There are many others who believe the era of great pop music has passed. Time will tell.
