The system is broken
I've been on YouTube for about a decade and the long story short is that the system is broken. The copyright laws are different in different countries, and that's always going to be the way while the world is, as it is.
The automatic take down system is a complete pain in the neck. I've had to fight a number of false positives and had my channel put at risk as a result.
Some copyright owners get out the ban hammer, while others want a piece of the pie. (and I do get the option, these days, to auto-remove the offending piece.)
It seems to me, that those generating their own arrangements and performances of music should be protected from the ban hammer. Yes, take a slice of the dosh, which is the way that it's been done for years... look at James Last and his arrangements of popular tunes and traditional music, from which he made a career spanning decades, and ... what was it... 150 albums gold worldwide?
Those just posting original recordings... yes. ban them into oblivion.
"Last is reported to have sold an estimated 200 million albums worldwide in his lifetime (figures vary widely, for example British Hit Singles & Albums (2006) reports 100 million at that time), of which 80 million were sold by 1973 - and won numerous awards including 200 gold and 14 platinum discs in Germany, the International MIDEM Prize at MIDEM in 1969, and West Germany's highest civilian award, the Bundesverdienstkreuz (Order of Merit of the Federal Republic of Germany) in 1978." - https://en.wikipedia.org/wiki/James_Last
