I've done

Marino (artist): ACTS - is the subject of the video, as the creator is rating their songs. Removing this would change the video's topic. BoyWithUke (artist): ACTS - is the subject of the video, as the creator is rating their songs. Removing this would change the video's topic. Laylo (platform): APPEARS - the creator's bio link leads to this platform, but it is not used or demonstrated in the video. Removing it would not change what happens in the video.
