If you are using a Broadcast API provided by TuneIn, which would look something like this, http://air.radiotime.com/Playing.ashx?partnerId=&partnerKey=&id=&title=song title&artist=song artist, it can be used to send updated metadata from RadioBOSS, using the built in encoder, to TuneIn to be displayed. If not, you can request a Broadcast API from TuneIn https://cms.tunein.com/broadcasters/api/. Your Broadcast API is placed in the "HTTP GET reports" under "Reports", in the "Settings". This will send the song metadata using TuneIn's album art database. For your original programming, like talk shows or shows using station talent names you need to send TuneIn a schedule consisting of the time, program name, and any program artwork. The TuneIn update page is https://help.tunein.com/contact/update-station-HyB_TSOf . Metadata sent to other players need to be able to display the titles. For testing Winamp is a good player that displays title metadata. Do you have a station website with a player and what radio stream provider do you use?
