They probably already have happened/exist, but I think the whole idea of them seems like a lot of fun.
Basically, it would work the same way as with a DJ taking requests. But instead of a DJ, it’s a VJ — and instead of just music, it’s videos.
If it’s house party, hopefully there’d be one big screen, and some decent speakers as well. Say, surround sound?
Most bars have many TV’s, and would just show the videos all over the place.
The VJ would set up a queue/playlist, and preview the upcoming videos for quality control purposes, making sure the sound/video is up to acceptable standards.
People could pretty much request whatever they want to see/hear, but there’s the possibility for some parameters to be set.
For example, if it’s Friday/Saturday night, you can limit people to only request certain videos/songs. Perhaps stuff that’s more along line of dance-able/hip-hop-ish stuff…
Maybe certains blocks of time could even be designated for only funny videos/other non-music related stuff.
The sky is the limit!
