Lost most of a playlist and some tracks declared unavailable but are playable from the album they are on

Hi @Nicholas_Prettejohn ----- Thank you for the report and my apologies for the troubles here. In order to accurate evaluate this issue may I kindly ask you to please provide the following information:

  1. Can you please give us the details of your current setup as seen here.

  2. Can you please clarify this comment for me:

“I’ve spent a long time creating a playlist which has lost most of its tracks.”

What had occurred that caused the play list to loose tracks?

  1. How is your music being accessed? How is being stored (internal storage, external storage, nas)?
