The iPod turned 15 over the weekend. The Verge has a cool visual history of the icon device:

And while the classic iPod design was finally retired two years ago, and the remaining members of the iPod line are less important to Apple’s strategy today than they were years ago, it’s still an integral part of history, both for the company and the larger tech industry.

So here’s a look back at some highlights in the history of the king of MP3 players, from the physically scrolling plastic wheel of the original iPod to the smooth glass and aluminum of today’s iPod Touch.

And Nobuyuki “Nobi” Hayashi found the 20 CDs that were curated by Steve Jobs to give to journalists along with the iPod to test out the device:

Steve Jobs insisted that Apple has no intention of stealing away the sales of the music industry; remember this was way before iTunes Music Store. What Apple did to keep its word is buying same number of 20 CDs sets and gave it along with the iPod prototypes to the journalists.

It has been 15 years since then, and I thought I have lost them. But recently, as I was moving to a new house, I have found that set (shrink wrapped).

Below you will find the list of those 20 CDs which was carefully selected by Steve Jobs and the original iPod team (lead by Stan Ng). Enjoy!
