Cortana + Spotify integration is now live on Win10 releases from RS2 and later.
You can now use Cortana to control music playback on more of your favorite music apps (EN-US only). Starting with this build, Windows has enabled natural language compatibility for Spotify. This works on both above the lock screen (PC is locked) as well as below!.You can try queries like…
Play Christmas music on Spotify
Play my discover weekly playlist on Spotify
Play <Artist/Track/Title/Genre/Mood> on <AppName>
Play some Drake
Play Focus music
Play Rock music
Once music is playing you can ask Cortana what’s playing like this:
Hey Cortana, what’s playing?
Cortana will keep you posted on your tracks.
To start rocking to your favorite tracks just get the latest app update and sign into Spotify in the notebook under the music section.
At this time we still don't have plans to let users reset their taste profile histories. You are welcome to create a new account with a new email address at any time (no need to contact customer support). However, this isn't recommended as you're truly starting from zero and it takes some time for us to learn your taste profile.
