Does the Simulator Actually Play Music for a Music App?

Hi all, 

I'm working on a music app, and I'm making good progress.  I've managed to get songs to download to the watch in the sim, and the songs appear to playback correctly (eg. The duration of the audio is correct).  However, the sim doesn't play any audible music.  I'm wondering, is this just standard behavior of the sim, or I have done something wrong in my app?  P.S. I don't have a music device, so I have no way to test it.

Thanks!
