This would let me see if I have any interest in listening to an artist, (i.e.) Is it something I'm likely to I hate or not, Is it something I want to influence future suggested music and whatnot I really Liked discover and I'm fine with it being hidden away in the browse tab/app or whatever.
But - previewing a song without getting pulled out of a playlist I'm listening too is something I enjoyed and it seems broken or missing What's up with that? Please put it back = at least as an selectable option.
Really missing the preview feature. It was really convenient to be able to see if I liked something before it got added into the algorithm that gives those same discove recommendations which are based on things recently played. And thats not to mention being able to go back to the currently playing track.
