I went for a jog yesterday and decided to listen to Spotify. I also used a Bluetooth headset, so it was the first time I've run with three devices (iPhone, Apple Watch, and earbuds) completely wirelessly. I noticed that the Music app on the Apple Watch could only control iTunes music, not the Spotify music that was currently playing from my phone and broadcasting via Bluetooth to my headset. Is there a native way to skip to the next song in Spotify or Pandora from the Apple Watch? Thanks!
