Instant Mix functionality needs revamping

[andreasmolnardev]

I've just observed the following issues with the Instant Mix functionality:

• Jellyfin creates them across libraries, meaning the library you're isn't reflected in the queue created
• In offline mode, tapping on a song plays the wrong one - even when "Start Instant Mixes for Ind. Tracks" is disabled

In general it seems like Jellyfin's built in Instant Mixes are just too limited for Finamp.

This discussion is also related to the following issues: #1268 and #819 where @lukaslindnermusic , @kuflierl and I have already discussed this.

Similar feature requests do exist upstream on Jellyfin's feature request platform (links here and here), but I don't see any indications that this is planned to be implemented in the future.

I’m not entirely sure whether this should be addressed in Finamp or in Jellyfin directly, but one potential fix could be to filter the incoming Instant Mix tracks to only include those from the current library.

@andreasmolnardev thanks for your feedback. Instant mix not being library-specific is a known limitation of Jellyfin which I also don't like.
Sadly there's no easy way to filter the tracks, since the items contain no information about which library they're from!
If you use AudioMuse for improved instant mixes, that now has an option to only analyze tracks from a specific library, but that can't be changed on-the-fly. But if you have a "main" library that you use most of the time, this might be a solution for you?

Regarding offline mode, that bug should've been related to sorting by "random", and should be fixed in 0.9.20. Please give it a try!
