@craigmaloney as a fan of music (of almost every kind) I'm just amazed at how Shazam and the likes made my life richer (not talking about my wallet). Hear a song i like, 3 clicks and it's on my iPhone. I remember years ago listening the radio for hours hoping the dj would play THAT song I heard only once and desperately wanted to hear again, with my recorder ready.

Granted, it's quite superficial, but nevertheless... :)
