Perhaps emacsclient could have a timeout here?  I'm not sure what a
reasonable timeout would be, though, but perhaps that can be a command
line switch so that the user can decide.

(I haven't looked at the code; perhaps it has a timeout already.)

The problem in these situations is that AFAIU the daemon doesn't even
know that emacsclient is trying to connect, because it (the daemon)
doesn't process connection requests when it's busy.

You could perhaps do it yourself by deleting the daemon socket when
you play the music.

This is wish for the feature or proposal for Emacs daemon to somehow
signal to `emacsclient' to be busy.

We know that if there is no daemon there is environment variable to
spawn some editor instead, which could be like `emacs -Q' or even `vim'

If however, the Emacs daemon spawned by `emacs --bg-daemon' is busy for
example playing video or doing some other process, then `emacsclient'
cannot know about it and is waiting in background.

It would be good to provide some kind of a signal that main Emacs
process is busy so that `emacsclient' can know about it and for example
spawn the alternative editor in that situation. This feature could be
then enabled through customization or variable.
