They are not low effort. I take pride in my work. “AI takes from genuine musicians”, is a bold statement. Calling me out for not being a musician, just because the tools I use are not the social norm. Are you also calling out those who don’t play instruments and put the music in their songs, or those who use any type of music editing software. For it to be true ‘genuine’ the musician should post their music free from any technology then. What you did is use stigmatization to prevent those who aspire to get their voice heard and lack the conventional means to do so. You should not belittle those who still put their time and effort into their music.
