GEMA fee to be paid in German Market when using Spotify Widget in Apps?

[cjans]

Hello everyone,

I have a rather organizational question for the German market.
I would like to integrate the Spotify widget into my app. However, there is the 30 second song preview. We don't want to earn any money with this Spotify widget feature, but of course we want to earn money with our app.
Will we run into the problem of having to pay fees to GEMA like an commercial event organizer?
Can someone from Spotify please answer this question here? It's so difficult to get a response on this from Spotify.

Short description of "GEMA":
GEMA is called “Gesellschaft für musikalische Aufführungs- und mechanische Vervielfältigungsrechte”, and it is one of 13 so-called “collecting societies”. A collecting society is an organization, e.g. an association, that collects fees for its members for the so-called “secondary exploitation” of artistic works. ... So everytime you play a song "in an commercial context" you have to pay this additional fee.
