When I first got my iPhone 4, if I selected a song from the "search iPhone" screen (when you hit home twice), iTunes would start playing a playlist of all my songs, starting with the selected one.
I recently updated it to 4.2.1 (I don't remember exactly what I was at before). Now, when I select a song from the "Search iPhone" screen, iTunes starts playing a playlist containing only that song.
Is there a way I can get the old behavior back?
