Since you can add music videos to iTunes playlists, I have some music videos in my iPhone. And I usually just shuffle songs when I play music from my iPhone in my car. Well, the song I was playing just happened to be a video. As I was listening to the song, I decided to check my email, so I clicked once on the home button. Usually when I do this, the music will keep playing as I access something else on the phone. But this time, the music stopped as my iPod app closed. So videos can't continue playing in the background? Was it this way before iOS4?
