While I'm an occasional stream listener, I've been mostly away from tech for a month and only noticed the coverage in this video from TAETRO.
"a big problem for music producers on youtube" - TAETRO https://www.youtube.com/watch?v=A49EKpd5rrE
They talk about the Lofi Girl situation and also describe the same issue Fran describes but with sample-based music production (as opposed to sample-based video production). Even if you're using non-exclusive, royalty free samples, you can get screwed by another producer using the same samples.

This is another take on the broader issue of hyper aggressive algorithms being poor judges of Fair Use. Rick has a few great videos on the subject (any many more on making music).
