Here is a piece of software that is so cutting-edge I have no clue how it works:
He pressed a button on his iPhone, held it up to my desktop speakers, and within ten seconds it had correctly identified the music playing out the speakers as track 7 from "Richie Hawtin's DE-9 Transitions" album.
So I switched it to "The Castle Hall" from Ayreon's "Into The Electric Castle", which starts out with nothing but 30 seconds of odd swooping noises. Once again, in less than ten seconds, it figured out exactly what track was playing, displayed album art, a track list, a link to the iTunes store, et cetera.
This is BLACK MAGIC.
