likeall()

I got it working with https://github.com/aawezhussain/Youtube-Music-Auto-Playlist-Liker - updating the query selector ID and removing the liked conditional (none of my songs were already liked so worked for me)

Would you mind posting your fix?

I got it working by changing the following line:
const likeButtons = document.querySelectorAll('tp-yt-paper-icon-button[aria-label="Like"]');
To:
const likeButtons = document.querySelectorAll('.yt-spec-button-shape-next--icon-button[aria-label="Like"]');
