How do I change tracks and control music playback on the Xstream?

Press the On/Off button briefly to play or pause music. To skip to the next track, press and hold the Volume UP button (A13) for 2 seconds. To go to the previous track, press and hold the Volume DOWN button (A12) for 4 seconds. To restart the current song from the beginning, press and hold the Volume DOWN button for 2 seconds. (Page 5)
