Amazon has been slowly weaving music functionality into its Alexa assistant. That has made Alexa pretty great, creepy laughing notwithstanding. But Amazon is not done improving Alexa. A new update rolling out is turning Alexa into the perfect DJ.

The new update lets you request specific songs through Amazon Music in the most vague ways possible. You can now ask questions like, “Alexa, play that Drake song I was listening to last week,” or “Alexa, play songs from Miguel I haven’t listened to in a while,” and you will be treated with the very specific music you requested.

Alexa’s new functionality will apply to playlists as well. Just swap out the artist’s name for a particular playlist and your request will be granted.

If there is one downside to the feature it’s that it only works with Amazon Music. Alexa’s new skills won’t work if you use Spotify or Apple Music. It’s unfortunate but that’s the way companies are choosing to lock down their ecosystems.

As voice assistants become more fleshed out, it is functionality like this that will make them much more useful. Asking Alexa (or Google Assistant or Siri for that matter) to play a specific song is easy. But asking it to play a random song you played weeks ago with little details provides a glimpse into how useful voice assistants are meant to be.
