Adding all songs of a playlist to library
I want to add all the tracks from a playlist to my library (so that all my songs from a playlist can be listed in the 'songs' section).
I enabled the option 'Add Playlist Songs' later and now only the tracks that I add to the playlist NOW are being added to library, but I want the older tracks to be there as well.
There is neither an option to select multiple tracks and add them to the library.
Kindly help,
Thanks!
