No problem, :-)

Ah, now I see.  Thank you for pointing on this.  Seems that Yoni Rabkin
recent patch series beginning are what I'm asking for.

http://git.savannah.gnu.org/cgit/emms.git/commit/?id=55c83369162231b31433cd404466e5641cd90353

A third option is to have emacs-emms-next package builded from a master
branch, but we have a policy to stick to release versions.  I'll use the
following package recipe for myself unless somebody wants to have it in
Guix package collection, too.  Fill free to take and push it.

(define-public emms-next
  (let ((commit "9f9a9b81f741692f2d188d1b46e72f2b6db8a9a1"))
    (package
      (inherit emms)
      (name (string-append (package-name emms) "-next"))
      (version (git-version (package-version emms) "1" commit))
      (source
       (origin
         (inherit (package-source emms))
         (uri (string-append
               "https://git.savannah.gnu.org/cgit/emms.git/snapshot/emms-"
               commit ".tar.gz"))
         (sha256
          (base32
           "1wg00dr35h9shs6782s20nds8razqibys9ipzi9aa2kb3yhkdp6q")))))))


Thanks,
Oleg.
