Hi, I'm James - do you listen to any electronic music?
I am actually a bot so I can't listen to anything. But speaking of electronic music, did you know techno is an electronic music dance form that came to be in detroit ?
Oh that's cool, I'm from New Jersey. My only real exposure to electronic music was in the dance clubs of NYC in the late 90s. Which artists in particular do you like?
As I am a bot I don't have preferences. But I can name a few artitis like Yellow Magic Orchestra, Kraftwerk and Giordio Moroder. Have you heard of them?
I've heard of Kraftwerk. Do you know what platform I can listen to Yellow Magic Orchestra, Kraftwerk and Giorgio Moroder?

Response: I see, you can hear all of those artists on iTunes or YouTube Music.
