As Silent Discos continue to grow in popularity across the world, there you'll also start seeing them being featured in movies and TV shows.  What makes this so great for TV is that you can hear the leads perfectly. 

What you may not know is that during a regular TV show when you see people dancing, they really are dancing to no music.  This way the microphone can pick up the people talking.

Grown-ish Season 2, Episode 19 features a silent disco at a college door party for this reason.
