Itunes 12.2 format playlist as songs not working
With iTunes 12, playlists can be displayed as a Playlist (your current setting and it seems to be the default), or as Songs, Albums, Artists, Composers or Genres. Change the setting from the menu bar at View-&gt;View As, or use ⌘J to open Show View Options.

There is no dropdown for the how playlists are viewed.
