Virtually every time I read something discussing this subject there is always the observation that today's popular music is not up to the quality of years past. It is not my sole opinion but that of many others, some in the business and some outside. My point though is that it is a popular opinion.
Radio is between a rock and a hard place. Being an ad-supported industry it has to appease both its listeners and its advertisers. It appears to me it is having a very tough time doing both. And worse, there doesn't seem to be a solution on the horizon.
I'm right behind Landtuna age-wise (and live in the same area) and share these opinions. Most of the music I listen to now comes from CD's or an MP-3 player. I buy used CD's most of the time. Yes, I'm not supporting the artist of my last purchase, but last time I checked Glenn Miller was still dead...
