Nothing against Tiësto
Hi, I'm Jérôme, a professional software developer and solve complex problems every day.
Each week I become more and more annoyed seeing tracks of artists I didn't like in my “Release Radar” playlist on Spotify.
I hit “Hide song” each time and roll my eyes the next week because Spotify's algorithms don't get it.
I finally bothered to web-search if it's possible to block artists, and of course it is.
As it turns out, all I had to do is to go on the artists profile page, hit the three dots and then “Don't play this artist”.
I could have thought of this myself, but it obviously was too easy.
