> they do a ton of things to siphon listeners that came for my music away from listening to my music, including NOT playing more of my music after the intended song plays.

I understand the criticism that it's hard for you to get an audience to notice you. But once somebody has listened to a tune of yours and then doesn't actively seek out more of it ... could it be that they just prefer to listen to something else instead? Competition is toughand it may feel easy to blame it on big tech, but sometimes peoples taste is just not something you can legislate..
