iHeartRadio lets you control when you are publishing to Facebook through the Publish to Facebook Timeline feature. When publishing is “On” in the player, we will publish your listening activity to your Facebook Timeline. This includes the radio station name and the songs that are played on that station. If you do not want any listening activity to be published to Facebook, click to turn publishing “Off”.
Please note: the Publish to Facebook Timeline feature does not control your listening activity on iHeartRadio. You can control that here
