Reason get_artist sometimes doesn't return songs

[Schtenk]

Hey, i'm not sure this is the correct place to put this but I think I know why get_artist sometimes doesn't return songs.

There seems to be two different "channelIds" per artist.
both of these works to get an artist except one does not include songs.

• ChannelId

This i is the one this api saves as "channelId"

This type of Id for for Mariah Carey is: UCurpiDXSkcUbgdMwHNZkrCg

This is the one found at the jsonpath:
header.musicImmersiveHeaderRenderer.subscriptionButton.subscribeButtonRenderer.channelId

Using this one in a new request no songs are included in the response.

• ChannelId/ChannelBrowseId

This is the one that youtube itself seems to mostly use which can only be found on songs/albums/singles or "More" buttons in the response.

This type of Id for Mariah Carey is: UCKRnq8aBOCanYlffje7HyvA

On songs/album/singles it is found in the above form^

From your library "More" button its in the form of:

• MPLAUCKRnq8aBOCanYlffje7HyvA

And on all other "More" Buttons its in the form of:

• MPADUCKRnq8aBOCanYlffje7HyvA

The full jsonpath may look something like this (MPAD version):
contents.singleColumnBrowseResultsRenderer.tabs[0].tabRenderer.
content.sectionListRenderer.contents[1].musicCarouselShelfRenderer.
header.musicCarouselShelfBasicHeaderRenderer.moreContentButton.
buttonRenderer.navigationEndpoint.browseEndpoint.browseId

Using this one in a new request songs are included in the response.

Responses are also slightly different, for example ShuffleId is under "watchPlaylistEndpoint" (for channelId) instead of "watchEndpoint" (for channelBrowseId), same for RadioId.

found that videos are also missing when using "channelId"
