A musical dream come true, the fourth-generation iPod offers voluminous capacity, letting you easily slip up to 10,000(1) songs in your pocket. And enjoy them wherever you go. In the car. On the treadmill. At the office. Around the house.

Though ease of use has always been the hallmark of iPod, we believe in constantly moving perfection forward. So iPod now incorporates the same touch-sensitive Apple Click Wheel that debuted on iPod mini. Without lifting that trusty thumb of yours from the wheel, you can easily select playlists, scroll through thousands of songs and start the music playing. Want that song to play from the beginning again? A single click will do the trick.
