There are things in this life we have exactly no control over. One of them is whether a radio station we like has the business model which will allow it to sell enough advertising and stay on the air, providing us with free music of a style we like to listen to. All too often you will find some new station that plays a great (to you) mix of music, put it on your presets and listen away happily until that day where you turn on the radio only to find some other station is there, with different music.
