Sorry, I don’t understand the question.
If you’re talking about the Playlist feature, you can cue up tracks and then make them live once they play in rotation. There’s a “cue” feature in the Playlist admin when you add a song that will hide that song until you change the setting, then it will display in the Playlist or the Playlist Widget. Is that what you’re asking?
Not sure what you mean by “DJs cannot play requests.” You can certainly play a request and add your request to the playlist as a cued track and then make it live when it’s actually on the air.
Radio Station does not sync to any radio station automation software…yet. In the future, we may have some automation software integrations.
