I think something like this might do it:

  (defun my-emms-track-desc (track)
    (or
      (let ((meta (emms-track-get track metadata))) (when meta (car meta)))
      (emms-track-simple-description track)))
  (setq emms-track-description-function 'my-emms-track-desc)

Idea there is to use first string from the "metadata" attribute that
you have attached to the track, if it's there, and otherwise just
fallback to default emms-track-simple-description generator.
