Not sure if it's good to put the videos in the 36787 audio kind.
I definitely want music videos on nostube, but with the current format I can not easily filter audio events for video content.
I have uploaded some music videos as kind 21 and 34235:

Maybe even for different audio formats (mp3 / flac) but especially for multiple urls (redundancy). It would also be good to add x tag for blossom sha265.
Have a look a NIP-32 for the L=ISO-639-1 spec to tag languages. That would allow filtering in a standard way.
Great to see we are moving forward on the audio front.
