Review title: Backlight Limitation
Product review: The music sounds great on this model, but the backlight will stopped lighting up if the battery is half used. Music still play but the backlight don't lit up anymore unless new battery is installed. This makes it impossible to search for songs or navigate through menus in the dark. I contacted Sandisk and they confirmed this limitation on the m200 models, but they don't disclose this info anywhere.
