The normal Garmin Vivoactive 3 has the ability to control the music when the watch is connected over Bluetooth to the phone. That's very useful for example, in the public transport you don't have to take out your mobile phone out of your pockets. Unfortunately this just works with google play music and not with spotify. Even if you are playing music from spotify and then for example press "next" on the watch, spotify stops playing and google play music starts playing some random music. I think it's thats kind of a software bug which should not be that hard to resolve. I hope Garmin can correct this with a new software update :)
