Stupid question about the default music provider in Google Assistant

[OniKunIsGr8]

I don't know if I'm an idiot, my phone's buggy, or what, but when I try to switch the default music provider in Google Assistant, it won't give me the option to choose the generic music app (just called "Music"). I have basically all my music play through that app, and only ocassionally use Spotify or YouTube instead, so I'd really like to know how to fix this issue.

Here's an attached picture of the Settings screen, note the lack of "Music". I'm using a Xperia Z5 E0665, if that's of any importance.

If you're an idiot, then we're two... Same situation here. Used to be OK in previous OS versions...

Are we idiots too thinking Sony's support will ever take better care of its clients ?

I'll escalate this but it seems to scan cloud services, which makes sense that Spotify it's there and not the default music app.

Also, keep in mind that Sony it is not in charge on this feature, that's on Google.
