I don't have a smartphone, and don't expect to have one ever, but they do amazing things.
A friend in South Carolina sent me a video clip that had an audio track that I found beautiful. I asked him what it was. He didn't know.
But he played it into his smartphone, on which he had an app that identified not only what the music was, but also the singer!
It was an aria from the Italian opera-movie La Califfa
, score by Ennio Morricone, and was sung by Sarah Brightman. I had recognized the voice, but had no idea what the music was.
It blows me away that a smartphone could do that. Here's a link so you can hear the song if you like.
She's pretty, too.
