The feature to push artist - title to Twitter will be removed from Spinitron soon.
This is the special feature in Metadata Push channels. You had to authenticate in Admin: Integrations and then use the twitter: pseudo-protocol in your push channel config.
It was always a kinda goofy idea. Who wants to follow a Twitter user who tweets every song on the radio, every few minutes 24-hours a day for ever?
Around the time that Musk took over Twitter and fired everyone we got reports from a few stations that Twitter was rejecting API calls from Spinitron. These accounts were being marked as bots in the great bot mind-control hyperventilation of 2022/3. There was no way to fix that. We pretty much stopped supporting the feature back then but didn’t remove it. We’re removing it soon as it has become a bit of a problem.
