For future messages please always include the error messages.

Looking at the soundconverter package we see this:

    (arguments
     `(#:imported-modules ((guix build python-build-system)
                           (guix build glib-or-gtk-build-system)
                           ,@%gnu-build-system-modules)

       #:modules ((guix build glib-or-gtk-build-system)
                  (guix build utils)
                  ((guix build gnu-build-system) #:prefix gnu:)
                  ((guix build python-build-system) #:prefix python:))

       #:phases …
       ))

What you have is:

      #:imported-modules
      ((guix build python-build-system)
       (guix build gnu-build-system)

       ^— add ,@%gnu-build-system-modules here
       )

      #:modules
      ((guix build utils)
       (guix build python-build-system) #:prefix python:

       ^— wrap this in parentheses

       (guix build gnu-build-system))


Note that the license field is also incorrect.  There is no license by
the name “bsd-style”.
