Host your own live radio show on top of Amazon's large music library! Per the app description: "Your Mix. Your Mic. Amp is where people come together to create live, shared radio shows with the music they love."
Surprised to see Amazon taking a big swing at a very crowded space (live chat/spaces). The idea of being a radio DJ would be fun, but I can imagine other competitors entering the space as well.
