Clicking one of these buttons will switch your view to the corresponding "library", or collection of files.  Click the "..." button to see the other libraries that aren't shown by default. You can click "Edit" and check the items that you want to always be displayed. When you insert a CD or connect your iOS device to your computer, a button for it will appear in this row as well. You can quickly switch between different libraries by holding Ctrl (Windows) or ⌘ Cmd (Mac) and pressing a number key. For example, Ctrl+1 in Windows will open the Music library. This will display the media library along with all of your playlists in the sidebar. You can drag and drop items to and from playlists using this view. This will allow you to switch between methods for organizing your media. For example, if you are in your Music library, the default view is "Albums". Click "Albums" to switch to a different sorting method, such as "Songs" or "Artists".
