Spotify plays indefinitely even with computer off and without Spark.

Interesting note. 

When Devialet incorporated Spotify in the recent update, one can go through the Spotify software on a Windows laptop and port straight to the Phantoms without opening the Spark.  I thought this was a great design. You can still control volume through the remove or the Spotify volume control via the software. 

Interestingly, if I set it to loop, and then shut down the computer or put it to sleep without stopping Spotify directly, the music in the play list will just play all day long indefinitely.  

I don't mind that as it provides soft background music without having to have the computer on. 

I thought this is interesting behavior. not sure if it was intentionaly but it is not a bad thing.

Spotify works everywhere this way. They treat "spotify enabled device" as another player, so you pass your playlist to that device and it connects to Spotify servers automatically. After that you can use any Spotify player (on mac, pc, web, iphone, etc.) to control your current device.
