I'm pretty sure that I up until recently could ask Alexa to play a song on my Sonos (without having to add the word 'Sonos').

If I try it now, it just plays on my Amazon Echo Plus, unless I ask it to play on Sonos.

Example:

Alexa, play Everlong by Foo Fighters. (this then plays on the Echo Plus).

Alexa, play Everlong by Foo Fighters on Sonos. (this then plays on Sonos).

Isn't there a way where I can tell Alexa to play any song request on Sonos?

I'm using Amazon Music by the way (1st day using it).

I used to be able to do this with Spotify...I think.
