YouTube to once again allow users to post comments on these auto-generated videos

YouTube will now allow users to comment on music videos that are automatically generated. The change has been brought for both YouTube mobile apps and desktop client. The ability to comment on such videos, called “Art Tracks” has been re-enabled after a pause of two years. The change was noticed by some users in the past few weeks.

What are “Art Tracks”?
“Art Tracks” are automatically generated music/song videos. They consist of “the sound recording and the album art” to “ensure that YouTube has a complete music catalogue and appears in album playlists and in search results.”
