Tracks like 'https://api.soundcloud.com/tracks/9707800
' from playlist 'https://soundcloud.com/the-streets/sets/cyberspace-and-reds-deluxe-edition
' which is now considered an album, but is not restricted to SoundCloud GO, is returning 403 when using a 3rd party client ID. When fetching the playlist itself, the tracks array is empty. This is new to the last few weeks as far as I know.
This means to 3rd party apps, content like this is now invisible (like content related to Go has been, depending on API endpoint, since Go started).
