The appearance of the iPod on my personal gadget horizon some years ago changed the way I listened to new music. Rather than buying a new CD and listening to it immediately, I would buy it and rip its contents into the churning stew of my iTunes library, where its individual chunks would bubble to the surface in the "Shuffle" feature's own good time.
Hence, me driving down the road a few weeks ago and hearing a track that caused me to think "Oh, wow, that's beautiful... That's got to be Moby..."
And it was...
...and in that short time, it's become the 23rd most-frequently played track in my iTunes library.
