What he/she said. You can no longer browse your iPhone library and hit play on the watch to start playing music on the iPhone. The Music app is only for the Watch now.

You control the iPhone with Siri and Now Playing, but you lose the ability to browse and see artwork now. Fortunately, you can access AirPlay options from Now Playing.

I would love to use the updated heart rate info, but don't want to lose my option to view music on from my phone on my watch, because it's so convenient to do so at work. If I had the 3rd Apple Watch, which has a larger hard drive for music, then it wouldn't be an issue. However, I have series 1 (which I got a couple months ago), so it's more convenient the old way
 
Any idea why there hasn't been more coverage on this? Prior to upgrading to watchOS 4 I didn't see this loss of feature reported on by any of the major sites.

I've left feedback, but it's really hard to know if they read any of those emails.

Somewhat foreboding is the fact that many apple watch owners with whom I've spoken didn't know the feature existed in the first place.
 
This is a deal killer for me.
Couldn't I just keep the S2 and never do the update? I'm assuming the S3 comes with OS4 installed, right?
How about, if you have an S3, could you not unpair the watch from the phone and play all your library from your phone to headphones? (like you didn't have a watch) You'd lose control from the watch but at least you'd have access to every thing in your library. Seeing and controlling my library from my wrist was why I got a watch in the first place.

Just cancelled my order for an S3. Now I have to decide whether or not to keep the S2.
 
Try NePlayer Lite. I connected AirPods to iPhone and am now able to play & navigate music from iPhone (through NePlayer Apple Watch app), maybe Apple will change their mind.
This is a ridiculously expensive app! $23 AUD! And I assume you can control music playback stored in that app instead of iTunes music library.

There’s a Lite version for free. It only works with non DRM files. albums! Works with Apple Music files. They are both much slower than the native watchOS 3 app though.
 
I got an email message to a change.org petition to have the feature restored and Apple has agreed.

I have chatted with an engineer at Apple after hours on Apple support. He has confirmed that iPhone music control will now be RETURNING to Apple Watch. I want to end this update with this. I never could’ve gotten here without you. Me a single customer could never been considered to even talk to the software engineering team let alone convince them to restore a feature. Apple is such a big company and I never could have thought this would’ve happened, I’d just like to say thank you again without a petition of about 1000 people I would have been a joke on the phone. I will officially declare victory on this petition is when an update with music function restored is officially released to public

It’s nice to have the feature back.

Didn’t realize how much useful it is to have... they even implemented AirPlay support with it too. I have two Libratone Zipps that I had to AirPlay... and it’s nice to be able to stream music to the speakers from the Apple Watch.

I recommend to buy some AirPlay speakers... it comes in handy with this new update. I’m just anxiously waiting until AirPlay 2 is supported.
