What is a “music reactor”?...............
There are a lot of YouTube “reaction” videos where, for example, someone will watch a famous movie like Airplane for the first time. Or listen to Bohemian Rhapsody for the first time. We get to see their reactions. If you get a certain number of subscribers your channel will be monetized.
It’s kind of lame, but it can be fun to watch a Gen Z-er view Blazing Saddles for the first time.
It’s a thing... You can get really cought up in them too. Just people making comments on YouTube as they listen to songs.
