FM Streaming URL Defaults Into Song

In the past, I have picked an FM radio station, put the url into open streaming, and then the stream opens into what I've labled as "Internet Songs." However now, I do the same procedure, and the stream defaults into "Song" in iTunes, and won't open to play. What am I doing wrong, or how do I get the stream to open and play in my "Internet Songs." Thanks for any help.
