When I try to play songs from some imported playlists. Most of the songs are greyed out and listed as unavailable. I get that spofity can't find the local files, but songs with the same name, same artist, same album are available as streaming. Spotify should be smart enough to figure that out and in the past it has been for the most part.
To reiterate, I can find songs with the title, artist, and album streaming but Spotify says it is unavailable while in the past it had no trouble.
