1 - when I press Delete on a song inside a playlist in order to remove it, the song isn't removed. In fact, nothing happen anymore when I press Delete.
2 - when I add the same song multiple time in a playlist, the new Spotify doesn't warn me about doing it. Since the update, it's a mess. I want that simple feature back, please. My playlists are long, big playlists. I don't want to add the same song again and again without knowing it.
3 - I liked the fact that I was able to set myself the size of the different part of Spotify. Now, the column on the left part isn't changeable anymore. That sucks hard.
