Why on earth do i have to select 15 artists

Hi ​@f23 !

Deezer requires you to select 15 artists initially to personalize your music recommendations and optimize features like Flow, which uses your preferences to suggest new music. This initial selection helps Deezer understand your taste and provide a more tailored listening experience from the start, including features like Flow. 

You can always change your favorite artists or explore new music through Deezer's other features later, so this initial selection isn't permanent
