I do this regularly with my Pebble. One of my side gigs is acting as the announcer for a colorguard contest (basically a dance contest with flags) and for sound checks, I can run Spotify on my phone, run around the gym listening to speakers, and control the music from my wrist. This is super useful, as I'm usually setting up the sound equipment by myself and don't always have a reliable assistant.
