welcome to the community, guardiansock!~
MV or Music Video in the disambiguation could be useful, even if the Video type is checked, as there could be multiple types of videos for a particular song (such as visualizers and lyric videos) or multiple music videos for one song (which is why I usually use at least “official music video”)
in general, I personally would move MV to the disambiguation. I think it never hurts to have a disambiguation, especially in cases like this
how MusicBrainz handles music videos is currently in discussion here, if you have any input:
