There are two ways to permanently delete playlists.

From the 'Playlists' tab (permanently delete multiple playlists):

1. Tick the boxes of the playlists you want to delete permanently.

2. Select 'Actions' and select 'Delete Permanently'.

3. This will delete the playlist from website and all signs (not undoable).

From the Playlist editor (permanently delete this playlist):

1. Select the 'Playlists' tab.

2. Select a Playlist Name (don't tick the box).

3. Select 'Menu' and 'Delete Permanently'.

4. A notification will appear at the top of the playlist, and the playlist will be deleted from all signs, but at this point it is still possible to recover this playlist on the website. Just select 'Save Playlist'. However, if you navigate away from the playlist editor without selecting 'Save Playlist', the playlist will be permanently deleted from the website (not undoable).
