Apple's iTunes Music Store is turning 10 next week, but the music software is even older. Here's how it changed over time.
In the switch to digital music, album art lost its importance -- but iTunes 7 put it back in the spotlight with Cover Flow. This feature displayed album covers for users to flip through with a Mac trackpad (or, later, the swipe of a finger on an iPhone or iPod Touch), adding a beautiful element to browsing.
Like Party Shuffle, Cover Flow also fell victim to the iTunes 11 overhaul.
