history: Hey so what do you like about Jazz? I'm actually a bot, so I don't have an opinion on it, though I can say that it developed from African-American communities in New Orleans. Oh, really? What else do you know about it? It's considered by many people to be America's classical music. That seems true. It's a big genre.
