Create a Zone.
Stretch the newly created Zone around a room or building of your choice.
Give the Zone a unique name in the entity properties such as:
Enter a stream URL in the User Data field in entity properties such as:
Simply paste the url below in the Script URL in entity properties:
Once STEP 5 is complete, if you create additional Zones you will NOT have to repeat STEP 5 by repasting the Script URL in a new Zone. You can simply repeat the below steps for a new Zone to have a unique stream in each new Zone:
STEP 1, STEP 2, STEP 3, STEP 4
When you enter a Zone, a sound player UI will pop up allowing you to play, stop and volume + or - for the associated stream in the respective Zone entity.
This will allow you to have a music stream player in as many zones on your domain as you like.
Please touch base if you have any questions. Thanks @chris for suggesting I create a brief tutorial on this.
