YouTube Music allows you to make your profile public and show what you're listening to

YouTube Music users can now make their profiles public and more informative. So, on the user's page, it will now be possible to see which songs, playlists, artists or clips he has been listening to or watching lately. But only on condition that the person himself agreed to share this information.

YouTube's settings now have an "Enable Public Statistics" section, where you can choose what will be displayed on your profile. For example, access can only be granted to playlists or artists, but not to songs and videos.

YouTube notes that if more information can be shown in the profile in the future, these options will be turned off by default. That is, you do not subscribe to share something in the future, allowing the display of existing options now.

Revoking permission will immediately remove the information from the profile. In addition, after 2 years it will automatically revoke: if you want to continue to keep the profile open, you will need to go back to the settings.
