Hey @Stylo only way would be to exclude those tracks from recommendations as you can see here: https://support.deezer.com/hc/en-gb/articles/360004367258-Exclude-an-artist-or-track-from-Deezer-recommendations

Listen, it doesn’t make any sense to dislike those songs after Christmas as that would mean i need to dislike 100s of songs. Nor does it make sense to dislike artists as that would exclude Elvis from ever playing or Sinatra etc

On top of that, why would i waste time hitting all those buttons for like 2 months, when the end of year comes ill want to play all of that again, so u might end up with not having those songs in my playlist or flow. 

Can you not just tag them with holiday season and just remove it afterwards? 

It is really annoying listening to Christmas songs in April, common this is really bad, really really bad, as it makes the flow unusable, or actually any PL that is created on the fly as some holiday themed songs will jump in after Massive Attack. 
 

You need to address this, not shove it under the carpet!
