Are you trying to view newly added songs into iTunes as the song view only and not some other view such as playlist? Set the default view by doing the following.
1. In iTunes, open the View menu.
2. Select View As and then Songs. (As pictured above)
By default, iTunes will remember your last selection view for future and the next time you add songs into your library. The songs view is mush more organized and offers better manipulation of your iTunes media.
