When Amazon first launched its original Echo in 2014, the company struck gold with a hit device and ushered in a new era of voice computing. It not only put Amazon at the front of a voice-assistant race with Apple, Google, Samsung and Microsoft, but it also gave Amazon's music services a plum gig -- sitting on top of the most popular smart speaker with one of the most popular voice-command helpers. 

Amazon has been pushing Alexa to be more conversational previously, with features like Hunches (which allows Alexa to ask you, for example, if you'd like to turn off the light when you say "Alexa, good night") and multistep requests. But music playback is one of the top uses of Alexa and Echo speakers, adding that back-and-forth dialogue to music discovery is a meaningful attempt to push Alexa forward.
