Yes, I would say unfortunately and I've been hesitating a bunch of this one. Let me explain. - When you play your local music, every time a track is about to end, LMS sends the request for playing the next one. It does not include metadata, but the bridge is gathering it using CLI - When you play a radio live stream, some stations like RP sends metadata update using the ICY protocol every xxKBytes transmitted. LMS gets it and displays it. The caracteristics of live radio is that they have a remote flag set and a duration of 0. In that case, the bridge queries LMS every 5 seconds to see if metadata update happened and it did, it updates the AirPlay device - Unfortunately, and I'm guilty here, with your plugin, the duration is not 0 anymore so the metadata polling does not happen. I've tried to guess the end of song using estimated length but it does not work very well. I think there is a mechanism in the CLI to subscribe to changes, but I've never used it and anyway it would force me to keep the CLI socket open which I purposely did. So this is the reason why you don't see updates. I will re-think about that over the weekend to see if I can still, in the case of remote streams, do the subscription or find out a way to keep polling but do a better job with estimated duration (like getting metadata at the end of the estimated duration and if they have not changed, keep polling for N times every 5 sec until a change is seen - there is some difficulties here around keeping an absolute / relative time reference) LMS 7.7, 7.8 and 7.9 - 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB2.
