Cloud Music Library playlists can only contain songs from your Cloud Music Library.
I recently moved my iTunes library to an external drive and successfully updated all the music files to the file location. Just tried to add a song to a playlist but received the error message below. I have the Sync Library checked, this song is in my iTunes folder, I don't have issues with other songs (so far). The song is AAC audio file, size is 3.2mb and the bit rate is 128 kbps. What am I missing?
