What is this stupid thing? Why can't I scroll through my playlists anymore?

I liked having that feature so I could listen to the highlights of songs and see if I wanted to add to my playlists but they changed it to...this???

No, I don't want to add songs to my playlist, that's what the 'quick add' thing is for at the bottom of my playlists.

This is such a weird and stupid thing to change, can I get the old one back in any way?
