Seems the formula is Rhythmic formats with small repetitive playlists with each song researched tested by small clueless groups (old chart history be damned).
Unless a station is switching formats, it uses an independently recruited sample of its own heavier listeners. They are invited, in exchange for money or some valuable reward like a $100 gift certificate or similar to "log in" and score on a sliding scale a bunch of songs.
Depending on the format, it might be a few hundred for CHR, or as many as 800 to 1000 for a Jack-type format and somewhere in between for country or classic rock or classic hits.
Old chart history, is, indeed totally "damned" as that is irrelevant today. What we want to know is "how much would you like to hear that song on the radio today?"
I went back and picked a chart from a station I loved to listen to many years ago. Of 40 songs, there were fewer than 10 I'd like to hear again now, and even less that I can say I'd love to hear again. There are about 20 I'd hate to hear again, and another 10 that I'm indifferent about. I don't hate them, but don't love them.
Stations want to find those few that I'd like to hear again today. Not the rest.
So let's say a classic hits station covers about 15 years of music. Maybe around 150 new songs got played in a year on the local CHR station back in the day. 30 or 40 stiffed without even getting into the top 25 songs in the market, and probably less than 50 ever made the top 10 and got played as powers. That means that there are around 700 to 800 songs from those 15 years that made it up to the higher places on the charts.
Of those 700 songs or so, you will find that several hundred... at least... are just uniformly rejected when you ask "how much do you want to hear that today?" So we are down to around 400 to 500 songs, and about half have the highest scores. You will play the big ones more than the weaker ones, but you are still playing only about 25% or less of the songs that charted back in the day.
Probably a good time to get out of radio stocks. Religious doom and gloom preachers and tropical shortwave station owners are probably salivating at the chance to pickup an NYC FM properties on the cheap in the not too distant future to simulcast with their shortwave outlet after the consultants burn NYC radio to the ground.
There have not been any commercial "tropical" (whatever that means") shortwave stations for decades. The rest of your thesis is absurd
I would assume that if you were sued for something like plagiarism or copyright infringement you'd hire a lawyer, right?
You said, "yes" I assume.
Well, a program consultant is like a lawyer or any other skilled authority. You call on them for added knowledge and experience. Most radio consultants are success-proven experts who guide your staff in putting together a winning format that has real strength in the ages advertisers seek. Right?
It is really at a point where why would an individual not stream for music given the blanding of FM formats on NYC radio.
Radio is "one for many". It can't be the same as your personal playlist of favorites. But it is convenient, easy to use and over 85% of Americans do just that every week.
