Usage

How do I add a song, album, artist or playlist to my library?
-------------------------------------------------------------

* **songs**: edit_song_library_status . Liking a song using rate_song
  does *not* add it to your library, only to your liked songs
  playlist.

* **albums, playlists**: rate_playlist

* **artists**: subscribe_artists . This will add the artist to your
  Subscriptions tab. The Artists tab is determined by the songs/albums
  you have added to your library.

----------------------------------------------------------------------

* **songs, videos**: "RDAMVM" + "videoId"

* **playlists, albums**: "RDAMPL" + "playlistId"


How can I get the shuffle playlist for a playlist or album?
-----------------------------------------------------------

Use get_watch_playlist_shuffle with the "playlistId" or
"audioPlaylistId" (albums).


How can I get all my public playlists in a single request?
----------------------------------------------------------

Call get_user_playlists with your own "channelId".


Can I download songs?

You can use youtube-dl for this purpose.


YouTube Music API Internals
===========================


Is there a difference between songs and videos?
-----------------------------------------------

Yes. Videos are regular videos from YouTube, which can be uploaded by
any user. Songs are actual songs uploaded by artists.

You can also add songs to your library, while you can't add videos.


Is there a rate limit?
----------------------

There most certainly is, although you shouldn't run into it during
normal usage. See related issues:

* Creating playlists

* Uploads


What is a browseId?
-------------------

A "browseId" is an internal, globally unique identifier used by
YouTube Music for browsable content.


Which videoTypes exist and what do they mean?
---------------------------------------------

"videoType" is prefixed with "MUSIC_VIDEO_TYPE_", i.e.
"MUSIC_VIDEO_TYPE_OMV". Currently the following variants of
"videoType" are known:

* "OMV": Original Music Video - uploaded by original artist with
  actual video content

* "UGC": User Generated Content - uploaded by regular YouTube user

* "ATV": High quality song uploaded by original artist with cover
  image

* "OFFICIAL_SOURCE_MUSIC": Official video content, but not for a
  single track


Why is ytmusicapi returning more results than requested with the limit parameter?
---------------------------------------------------------------------------------

YouTube Music always returns increments of a specific pagination
value, usually between 20 and 100 items at a time. This is the case if
a ytmusicapi method supports the "limit" parameter. The default value
of the "limit" parameter indicates the server-side pagination
increment. ytmusicapi will keep fetching continuations from the server
until it has reached at least the "limit" parameter, and return all of
these results.
