Hi @Leyo91, thanks for your message.
Have you tried use the Flow mood wheel ? Just to see if you have any improvement.

Or simply dislike those tracks if they are unwanted. This will train the algorithm to understand what you prefer!
Also I suggest for you to access this article How Deezer built the first emotional ai for you to learn more about Flow. 

Mood works expect for focus mode that use soundtrack music, but if I want a generic Flow the player is only soundtrack music. I have over 140 artist (pop, dance and electric), only 2 or 3 artists are a composer like Hans Zimmer, I don't understand, until a few days ago everything worked perfectly, the music was varied

Hi @Leyo91 sorry for the long wait.
