Playlist to play all audio and soundcloud
Design and Skin Customization
One way to do it could be to add another form field to the audio files via the Form Designer that only the admin can see, make it a text field and the admin enters something there.>>
then use the Batch Edit module to go through and update all the audio files with which radio station they are at.
If you called the field audio_station and set them as numbers 1, 2, 3 etc, then use that in player search
{jrCore_media_player type="jrAudio_player_dark" module="jrAudio" field="audio_file" order_by="_created random" limit="50" search1="audio_station = 1"}
That would play all the songs in station 1, do the same for the others.
