When a playlist is deleted, possibility to also delete the tracks it contains from the collection

What is the feature or ability you would like to have?
When a playlist is deleted, possibility to also delete the tracks it contains from the collection, and even the files.

How will this feature help you and others?
For example, the playlist was created with the sole intention of classifying, organizing these tracks, and therefore it only makes sense for the tracks to exist if the playlist exists. If you can’t delete the tracks at the same time as the playlist, you can drive yourself crazy later to find the tracks you want to delete in the whole collection.

Is this feature available in an existing product? If so, what product?
I don’t know.

Does a workaround currently exist?
I don’t know.

You can hold the CTRL button when deleting tracks and it will ask you if you also want to delete them from your library (or disk). So delete all tracks, then the playlist and you should have what you want.

But…then…one more question, please:
If I have a playlist with a tree structure, for example:
List1
–Subfolder1
----SubSubfolder1
–Subfolder2
I’m at work and I don’t remember if I can list or display all the content of the root playlist (List1) to delete everything, without entering in each subfolder/subplaylist.

Yes you can, just try it at home
