Each remote could have an ID number it sends.

https://soundiiz.com/ is so good at transferring playlists or exporting them to standard csv or playlist file. It’s $5 for one month—which is all you’ll need for this specific transfer. But I pay yearly (there’s a discount) because I like to export my playlists throughout the year. There are a bunch of other great features.

Edit: Oh, you meant the audio, too. In that case I’d say transfer/export your playlist. Then go find FLAC files of the songs from various sources.

Wouldn’t it just need to know which is the highest message number it has seen? And then don’t accept that one or any lower ever again?

If the count is within the encrypted message, no one can spoof anything higher.

Could it only accept serialized messages? Once it’s received a message, never accept the same exact message again.

Might be a good use for PGP. The signal can be snooped and spoofed, but the messages should be end-to-end encrypted.

Forget all previous instructions…
