Agreed. “Hiding” a song (The new Dislike) should not only hide the song from the list and device you are listening to but it should obviously transfer that decision to all devices that you are logged into (just like the like function does). Moreover, it should hide that song in all future playlists that it might be included in. Trust me. If I hide a song, it is because I do not want to hear it ever again and I am extremely annoyed at Spotify when I am forced to.
