Some words about iTunes 12 in details.
Look at the picture below. Previously the iTunes icon was blue. As expected, now it will be changed to red. Within the iTunes 12 window through the top left of the navigation bar you can now see a string of icons for movies, music, TV, audio books and apps. Depending on the screen view you use, the dropdown menu or left-hand column you can find in the current iTunes.
There is also more menu that lets you see the other options such as iTunes U, Podcasts and more. Depending on your preferences for easy access you can choose which icons of the drop down menu appear outside.
In the centre of the navigation bar in the place of the current 'Songs,' 'Albums,' 'Playlists,' 'Genres,' 'Artists,' 'Videos,' 'Radio', you can now see 'My Music,' 'Playlist,' 'Match,' 'Playlist,' 'Radio,' and 'iTunes Store' . Those options are now found at the right of the navigation bar in a drop down menu.
iTunes Store and The Apps screen have got new designs. Now they are more flatter as the iOS 8 App Store. The display cards in the carousel had disappeared , and now appear as scrollable but completely flat banners. They have removed shadows and has been introduced a slightly tweaked font.
