Airplay + Built in speakers simulcast.

[smplng]

Hey all,

I just discovered that iTunes allows me to listen to music through an Airplay device, in this case a Sonos Speaker, and the built in iMac speakers at the same time.

That's fantastic because the Sonos has very decent low end, and the iMac has a stereo image but almost no low end, so together it sounds real nice.

So as my music consumption is primarily through Spotify, I wanna ask if there's any plans of offering this through the OS app?

Thanks!
