The trendsetter page e.g. https://spotify-trendsetter.de/ is great but it seems to be not working properly. My brother for example had an artist (Dan Croll) in it, which I also heard from 2012 on but doesn't appear in my list. That raises the question how many other bands there may be missing?
Also: there was an individual trendsetter playlist recommended the previous days, before the web page went live, I think. That playlist was similiar to the recommended mix on every monday. I am looking for this specific trendsetter playlist - seemed to be nice but now it's gone in the dekstop app (windows). The playlist, which you can create on the website mentioned above, is a different one.
