ELI5: Why are music reaction videos monetizable on platforms like YouTube but not cover songs?
gpt
Basically because reaction videos fall under fair use, which encompasses satire or educational purposes.  A song cover can actually also be monetized, depending on how the property owner has set their preferences. In general, if your cover uses the original track in any way, the IP owner can chose to block, restrict, or redirect revenue generated by the video.
