Super Smash Bros. for Nintendo 3DS turns the 3DS into a music player by letting you choose songs from the game and play them from the handheld. The feature was announced via a Miiverse posting from developer Sora. WYou can listen to character voices, too, but one ofthe highlights of this feature is the "Play in Sleep Mode" option. If you turn this on, you can listen to the tracks with your headphones even when the Nintendo 3DS is closed and in sleep mode. The L and R Buttons will let you skip tracks. This means you can use it as a portable music player. Enjoy listening to the tracks you love by putting all songs in loop, shuffle, or selecting your favourite tracks.
