In the new look iTunes 11
Select your Album, Artist Song etc drag to the RIGHT and a window will open showing your devices and playlists. Drop it on the one you want to add it to.
Or revert to the old look and feel
View > Show Sidebar
View > Show Status Bar
Click on the arrow in search box and untick Search Entire Library
You can now drag and drop to the LEFT where you will see your devices and Playlists. You can also drag playlists to the device
i want to have one window that shows the results in the search field, select from that choice and drop into a window which contains a playlist.
the search menu should work like a finder so i don t have to go from one choice (artist, album, ect) to the second option.
right clicking the dropdowns does not allow the same options as the right click in the sidebar
so i need two windows in itunes.
You do not need two windows to move search results to a playlist.
Existing playlists show in the sidebar and you can select all the tracks that you want to that playlist. If you want a new playlist you can create one by selecting all tracks required and ctrl click and select option from pop up box.
