This is how I am attempting the deletion: payload = { "data": [ { "position": 0, "type": "library-songs" } ] }; const response = await fetch(url, { method: 'DELETE', headers: { 'Authorization': `Bearer ${DEVELOPER_TOKEN}`, 'Music-User-Token': USER_TOKEN, 'Content-Type': 'application/json' }, body: JSON.stringify(payload) }); The USER_Token was generated via: music.authorize({ scopes: ['library-modify'] }); I can successfully create a playlist and add to it using those tokens, so they should be OK. (this is in node.js) I can find no documentation for any track deletion API, this code is an approach I have seen in posts around the web, but I do not know if that method is in fact the right approach.

Thanks for the response. canEdit=true in my case, so I don't think that is it. Is their documentation on the DELETE method?

I can't get xcode 13.2.1 to connect to ios 15.3, even after downloading the necessary xCode files and rebooting everything twice. Anyone have suggestions?
