Describe the bug
get_liked_songs() function fails with KeyError: 'setVideoId' within the playlist parser when authenticated using a browser.json file with headers copied from the browser.

To Reproduce
To reproduce the problem, run the following with headers containing the HTTP request headers from a POST /browse request listing your liked videos on music.youtube.com:

headers = '<YOUR_YTMUSIC_HTTP_REQUEST_HEADERS>'
ytmusicapi.setup(filepath='./browser.json', headers_raw=headers)
yt = ytmusicapi.YTMusic('./browser.json')
likes = yt.get_liked_songs()

The get_liked_songs() call fails with the following error:

Traceback (most recent call last):

KeyError: 'setVideoId'

Additional context
The error happens only when using browser header authentication. It does not happen when using OAuth.

@sigma67 commented on GitHub (Oct 23, 2023):

You must be using different accounts, I don't see why there should be any difference between browser auth and oauth.

This is probably part of some A/B test, so I'm a bit hesitant to merge.

setVideoId is also essential to move items within a playlist, so the fix isn't to just ignore it if it's not there. Instead we need to find the new location within the data (or the new mechanism if it works entirely different now).
