Thanks for the information, I don't know where my subsonic playlists were saved. They don't appear to be in the subsonic folder on my C drive. A warning about this would have been nice, I certainly would not have upgraded.
They haven't been deleted - they are still in the same folder that you set up in 4.6 That would normally be in your media folders - not usually in the c:\subsonic folder
Everyone is entitled to be stupid, but some abuse the privilege!
Due to the confusion from too many genres of music, we have decided to put both country music and rap music into the genre of Crap music.
I upgraded to this beta version and had to go back because the beta would not import my original playlist. It only imported 1 but no more and when I created one I have no idea where it went. Plus when I accessed subsonic by android phone it said there wasn't any playlists. So these features are not implemented or they are broken.
