I agree somewhat with what you are saying. But what most people have to realize is that there are and were a lot of jocks out there who started out with no experience and became legendary jocks. So don't blame the Pd's for hiring people with no experience because that is not the problem. The problem is that the jocks are not allowed to be creative.
If you remember the Stoneman from the great days of PLR, he had zero experience until one day the on air jock quit, walked out of the studio and told the stoneman who was a salesman at the time he better get up to the studio or the station will go off the air The rest is history. So don't go after the people with no experience who are given a chance. Go after the corporate morons who stifle the PD's and the on air talent.
Another great idea! Lets put together a focus group , play them 7 seconds of a song and ask them if they like it. This will determine if this is a great song or not. GENIUS!!!!!!!!!!!
