Apple Watch Remote Old iPhone My setup is as follows:

I have the Apple Watch on my wrist, and I have an old iPhone 4s with iOS 8.4 sitting on a docking station

Can I control the music playing through the iPhone through the Watch? - I can control the music playing on my mac &amp; newer iPhone 6 but can't figure out, if possible, how to do it on the old one?
You can't control music on the iPhone 4s because Apple made it so the iPhone 4s doesn't support the Apple Watch.
