How to delete wrong music suggestions

[FamilyEitingVLiempt]

In the previous versions I could delete music that was suggested based on my earlier played songs. 
But the algorithm started playing songs that I have no interest in. And this now even triggered the suggestions of music in that same genre that I do not go want! 
In old versions I could give a thumbs down, but this is jo longer possible. All I can do is the contrary, thus exchange it for my current playlist, love it, play radio, etc. But I do not want them as suggestions and even want to have them out completely!
