I think there’s value in Likes. For me they’re just a way to let the author know I enjoyed their post. In my case they’re not mean to be public so I keep them unlisted.
Inspired by your Listens I added a similar section on my website, but it gets one post per month or whenever I mark a song as “Loved” on my music player.
As for TV Shows Watches, it might be a good idea to post only about completed seasons?
