Really!? Still not way to play music direct to Apple Watch without devices or bluetooth???

I have a Series 7 GPS / Data Apple Watch.

I can't understand why to this day.... Apple Watch won't support playing downloaded or streaming or downloaded Apple Music just through Apple Watch to the Apple Watch speakers. Meaning: No phone or other speaker / headphone devices required.

Amazingly, Shazam app on IOS can do it!!! But Not Apple's apps. Really!? No, Really!??

Please, if there is a beta I can participate in to have that functionality let me know. I would even get the jumbo Ultra Apple Watch if it did that.
