I'm using the Spotify's Windows Desktop Version. Not sure if my issue only applies to this version.
My Question or Issue
First of all, I don't know if this is the right place to post this, maybe someone has a better idea? Nevertheless, here is my point:
If you look at the attachment, respond to the following question: By pressing the marked buttons, which panel would swipe? The expectation, following Gestalt rules or the principles of grouping (like Proximity and Closure), would be that the upper panels ("Rock" group in the picture) swipe. The line below the buttons would also make you believe this. It clearly separates the two groups. But that is not the case, it's the lower ones that swipe.
That is very confusing! Is anybody else having the same issue? Let us inform Spotify about it and make it clear that it is not human-friendly!
