Yes this is only for the Playlist. The all music is perfect.
Another thing I did when transferring from old phone is I grabbed the exported playlist/backup file from the download folder where Poweramp put it and also went deep into android/data/maxmp and grabbed what I think is a .pla file.
So in my new phone in the "Playlists" storage folder I have a playlist .pla file, a playlist vlc file, and the playlist backup file I created. When setting up new phone I tell Poweramp to look in "Music X" and "Playlists". So I figured Poweramp will look in "playlists" and grab one of the 3 that it chooses as I don't know which one it wants. This might be where the issue is?
