As much as I hate it, I know why: Money.
The songs they play is advertising, radio is simply the medium and us listeners are potential customers. Stations make money by playing songs, playing commercials and hosting programs either relating to up coming concerts, give-a-ways, community shit, etc. The only way they can broadcast any of the above info is by talking on the air. But since the songs themselves probably rake in the most cash, they are limited from talking over the lyrics.
Besides, they assume that is they have a large listener base, of those people that matter bought CD
's to all the songs of their playlists, they don't need to hear every damnned song or the bits and pieces of them. I laerned in a business class about the 80/20 ratio, that depending on the market, 20% of the customers provide 80% of the revenue. Which means up to 80% of the listeners of a radio station are not targetted for sales; i.e. they will take your request for statistic purposes but not to play the song.
Most radio stations play only the popular songs either requested by those people that matter or sponsors or songs the industry dumps a hella lot of advertising money on. I have been observing my local top40 station, it seems to me that the record company that produced the song spends money to get the song played for the first 3 weeks, thereafter listeners will request it enough to both keep it aloft for months and continue sales. You gotta spend money to get money....
I for one hate the fact that the business industry has taken over every aspect of my life claiming it is to make it more efficient. In reality it is more efficient for them
. Take the drug industry, do they really wanna make your cancer go away? This is why I don't buy the Phillip Morris ads on TV
, it is almost like they are confident no one will give up on them; they're doing it for PR
, a few commercials a week is cheap anyway; look at the time of day they show them and what channels, they are staying away from the traffic zones.
The meaning of life is curiosity; we were put on this planet to explore opportunities.
