I used to request Tunein most time, then when I forgot I would sometimes get iHeart. It really doesn't matter it is the same station. But, I returned to saying tunein, and after a while the Alexa got trained that I wanted tunein, not iHeart, and today all I need say is to play station X and it plays on tunein every time. For now, say play station X on tunein until Alexa gets trained.
