Almost half my songs were removed from my playlist

[mattiman18]

So I had a playlist with over 1,300 songs, and all of the sudden it's down to just over 800. I still have all the files on my phone so I can add them again but I still want to know why this happened and if there's an easier way to fix this.

Thanks

Did you remove files from the Library and re-add them? That will remove them from the Playlists.
