Why can't iTunes sort the music that's on my iPhone anymore? I plug my iPhone into my MacBook Air and listen to my music with iTunes, but it seems that since the last update, I can't sort my music or open the browser with CMD+B. It's stuck sorted with the songs alphabetical by title. I can remove columns and add columns, but clicking on the does not sort by the clicked column. The four buttons near the top right don't change the view style either.
