Our distribution to iHeartRadio does not make you a searchable artist in their website.
Only artists who are both part of the internal catalog and also have their own artist station are listed in the search function on iHeartRadio.
Our distribution service stops at adding you to their catalog, and does NOT include creating an artist store.
That being said if you included iHeartRadio in your distribution options then your music IS with iHeart Radio and could be queue'd for playback in a different artist's station. It just cannot be searched for in their search bar.
Registering with All Music Guide may be of assistance in getting your music it's own artist store on iHeartRadio, however. You can sign up and read some more about submitting at the following websites:
