I have seen this article before. The author are so close to understanding why Spotify does NOT need a dislike button
>To dislike a song is easy – to like one, you have to actually invest time in it.
Likewise, to detect if a user dislikes a song is easy since the user will not invest time listening to it: the skip button is the dislike button.
In contrast, detecting if a user likes a song is more difficult: there needs to be a way to distinguish between a user enjoying a song and the user not paying attention (in that case the user will provide no input whether they like the song or not.)
