How do stations pick the songs they play???

[CRAZY-HORSE]

I would suggest different countries each have different criteria surrounding what material they play and more importantly, each station would have their own music format also...

I don't believe the artists have a say in what gets played, its probably more a case of their recording company and how money they want to throw in at promoting an artist....

I do know a guy who works at a community funded radio station and they are bound by the same laws regarding broadcasting as the larger radio networks,
In his case the broadcast law states that a certain percentage of songs played on radio here must be of Australian origin ie: The artist must be of Aussie origin regardless of whether they still live here or not...
He is also in total control of what he plays everyday as long as the above criteria is met and the music conforms to the station format....

I do notice that when an artist tours here, lets say Stones for example....
They seem to get more song played during the lead up of a tour than they'd normally get....
But,
Is that the DJs choice or are The Stones label promoting them?, I don't know.

What I don't like about the modern music stations is that they overkill certain songs and artists,
The most recent example is Taylor Swift,I like her music but, it seems every third sing at the moment is "bad blood", before that is was the other singles from the album....

I change which station I listen to every couple of days, that way I hear modern pop, alt, country, classic rock etc all the time which leaves no time to really get too stuck on one genre/format...
