This whole idea of what songs a radio station should play, and how often, really intrigues me because there is so much at stake, from a business perspective. Recently, I was solicited to particpate in a music focus groups but did not qualify after I answered some questions. I am sure my age, 55, did me in. I believe the demo goes 25-54. I would have loved to particpate just to see, in person, how such research is done.
I have also been listening to Sirius XM a lot since I bought a new car and a free 3 month trial came with it. I just wrote the check to renew it for another 6 months. It is a new toy for me so I love it. My favorite channels are The Bridge and The 70's. I am definitely hearing songs I no longer hear on regular FM radio but then again, the business model is very different.
Finally, I still listen to KRTH even though the music is getting younger. I probably always will...
