Start the sound and shake your smartphone - that's all you do in 'Move For Sound'. The music gets quiet when you do not shake, it gets louder when you shake. Just do it for fun! Do it to get a high shake factor! This is presented at the end. You can choose the default sound or choose your own music file to be played (.mp3, .wav, .ogg, ...).
Warning: Be careful while using this app. Permanent and intensive shaking could possibly harm your smartphone.
