Hi ​@jbrugger !

Deezer suggests playlists from sources such as your Favorite Tracks, Top Tracks and Suggested tracks, from your recent listening history and recommendations. 
If you don't have enough listening history or Favorite Tracks, the playlist will show a less interesting content.

Unfortunately, I  think that option can't be turned off and you must simply ignore .

No, it doesn't. I'm a fan of classic crossover music, gospel, and bands like ABBA, and the playlist suggestions include reggaeton. As you can see, they have nothing to do with each other.
I have the same favorites on YouTube Music, and it never suggested reggaeton.

I can certainly understand that it is annoying when the recommendations in Deezer are not good. May I ask how long you have been using Deezer?
And if it has been a while, have the recommendations been good in the past?

​@jbrugger !

It might be a good idea to contact Deezer support, maybe they can help you 

I have been a Deezer user for about 3 years.

I've been having issues with Flow's recommendations, but lately, while they aren't the best, they've been working pretty well. The problem currently is with playlist recommendations, which include artists and songs I've explicitly blocked.

I’m not sure, but wasn’t a kind of reset possible with your recommendations? Maybe ​@Nina Nebo or ​@Jaime.Deezer would know?

Hi ​@jbrugger as ​@Nina Nebo best thing to do is to contact our Deezer Support Team and one of our agents will be able to check your account and help with your request.
Apologies for the inconvenience
