eh most of the time if a station like the artist or the cd, they tend to play a few of the other songs besides singles. No one really cares. Here in America I have heard on the radio (take for instance Nine INch Nails new cd Year Zero) I heard other songs besides the single and also way before the cd was even released. ITs just how people can get stuff now a days. It just happens. I think the people [[record labels] get mad if the stations play the other songs other than singles a lot more than the actual single...
sorry that was a long reply hehe.
