Soundcloud might be an alternative worth looking into. For the music I tend to search for, I find I’m more likely to find it on Soundcloud, and it can take years to migrate from SC to YTM.
While YTM and SC were both $10, putting up with the worse platform was a reasonable price for no YT ads. Now that the grandfathering is ending and the price is jumping to $14, for US folks, I’m feeling the pressure to migrate.
Well, its most of the normal music and then a bunch of pirated music. It’s like YT music but with a better “Start Radio” button.
