1: Show Sidebar
Open iTunes and choose the View menu. Here you’ll be able to choose to Show Sidebar and Show Status Bar. Enable both of these options to return iTunes to its former glory.
2. Song View
Now use Song View and you can pretend like this is still the old version of iTunes. You can access all your media and playlists using the sidebar, and connected devices will also appear here, just like they used to in iTunes 10.
