iPod shuffle 1st Generation

Released on January 11, 2005, the first-generation iPod Shuffle weighed 0.78 ounces (22 g) and was designed to be easily loaded with a selection of songs and to play them in random order. According to Apple,[citation needed] owners of existing iPods had often left the music selection to "shuffle", and the new iPod Shuffle was a way of implementing that in a much more cost-effective fashion. It relies on the use of an "autofill" feature in iTunes, which can select songs at random from a user's music library (or from a specific playlist) and copy as many as will fit into the iPod Shuffle's memory.
