As soon as it came out, the $1,500 futuristic eyewear known as Google Glass became something of a punchline. But the technology now has some music apps that go along with it, and those apps seem pretty fucking cool. Using voice-activated commands, you can now identify a song that you might hear, find that song, buy it, and even search out a place to find that song on vinyl. And in the promotional video below, Jay-Z sound engineer Young Guru does exactly that, hearing a song in a Mexican restaurant and then finding that exact same song on vinyl.

Later this month, Google Glass will get its own cusomized earbuds, and you can read more about the glasses’ music functions at Rolling Stone.
