First of all, I created a playlist, clicked on the playlist, then tapped Shuffle so it would play the songs in random order. It did that, but then it also played some songs not on the playlist. How do I get it to only play the songs on the playlist? Also, when I was walking, the music randomly stopped. I've figured out that this happens if the headphones get jarred at their juncture with the jack. Is this a common problem in Droids?
