It's possible to use your Echo smart speaker to send song recommendations to friends. Amazon announced a music sharing feature that lets you share tracks with your Alexa contacts using Echo devices or the Alexa app. Tell Alexa to "share this song with" and state the contact. The recipient can listen to the song on whatever streaming service they have and send a reaction to it your way.
The voice assistant will try and look for the song on services available to you and your recipient. If it doesn't find it, it'll get a station based on the artist's name and song title. The feature requires you and your contact to have Alexa Communications enabled. Amazon said this is "just the beginning" for the sharing feature, so other sharing capabilities might soon be heading our way.
