The iPod Shuffle (stylized as iPod shuffle) is a digital audio player designed and marketed by Apple Inc. It is the smallest model in Apple's iPod family, and was the first to use flash memory. The first model was announced at the Macworld Conference & Expo on January 11, 2005; the current fourth generation model was introduced on September 1, 2010. And, it does not have a screen. Instead, you upload songs and it plays them at random.
