It's not easy to make a living as a full time performing musician these days so a lot of people are turning to other income. I find it odd that other musicians, especially on this forum and TOP are so anti anyone trying to bring in additional income on YouTube whether it is with reviews, lessons, shilling, whatever. It's all just another form of art/entertainment, just like playing music. If the alternative is less real music and more AI music, and I think that is reality, I think it's good that people can find a niche on Youtube to keep the bills paid.
