Amazon Music for Artists

Hopeless. There are several artists with the same name as me. My own ‘artist name’ did not appear among them on the list, even though I have well over 1 mill streams on Spotify. I ended up on a page that belonged to someone else - which it would seem I now ‘own’ (apologies to the guy who created it and probably does not have access anymore!). Anyway, the problem is, given that I now seem to ‘own’ this profile, there are a large number of songs there belonging to someone else. The only way I can get rid of them is by typing every single one of them into a dialogue box - but there’s tons of them. How am I supoosed to remember them all? And frankly, it’s just not worth the effort! Apart from this standard approach - which doesn’t work - there is no way to attract Amazon’s attention. So ‘Amazon for Artists’ has been a complete waste of time for me.
