I think it only show "any random video with music" if you've liked the video and it appears to be a legitimate music video (i.e. without dialog/non-musical noises etc.). I use YtM a lot and the only questionable videos are ones that I've hit like on (beat saber being a prime example - I've learned not to like anything like that, these days).
