Amazon today announced Alexa Cast to allow for better music control on Alexa devices. Users will be able to more easily transition from listening to through the Amazon Music app to listening to Amazon Music on an Alexa device. This is a much-needed function for Amazon’s core services.

Before Alexa Cast, it can be messy switching between listening to Amazon Music on different devices. The service does not have the same sort of controls found on other services like Spotify . It sounds like Amazon is finally building out features that will turn Amazon Music into a legit music service and Alexa Cast is a good step forward.
