Here's some code that I've been using that allows me to select a playlist from an EMMS buffer, load it into a new buffer when I hit "l", and switch back to the previous EMMS buffer when I hit "q".
I thought code was committed that could create and keep track of
multiple EMMS buffers, but I can't seem to find it.
(defvar my-emms-playlist-stack nil)
;; Load the playlist into a new EMMS buffer, saving the old one
(defun my-emms-playlist-load-playlist ()
(interactive)
(let* ((track (emms-playlist-track-at))
(name (emms-track-get track 'name))
(type (emms-track-get track 'type)))
(emms-playlist-select (point))
(sit-for 0)
(run-hooks 'emms-player-stopped-hook)
(when (or (eq type 'playlist)
(string-match "\\.\\(m3u\\|pls\\)\\'" name))
(setq my-emms-playlist-stack (cons emms-playlist-buffer
my-emms-playlist-stack))
(switch-to-buffer (setq emms-playlist-buffer (emms-playlist-new)))
(emms-add-m3u-playlist name))))
;; Remove the current EMMS playlist and set the old one as current
(defun my-emms-playlist-destroy-playlist ()
(interactive)
(when (buffer-live-p emms-playlist-buffer)
(with-current-buffer emms-playlist-buffer
(emms-playlist-clear)))
(let ((old emms-playlist-buffer)
(new (car my-emms-playlist-stack)))
(setq my-emms-playlist-stack (cdr my-emms-playlist-stack))
(if (buffer-live-p new)
(progn
(setq emms-playlist-buffer new)
(switch-to-buffer emms-playlist-buffer)
(kill-buffer old))
(bury-buffer))))
(define-key emms-playlist-mode-map "l" 'my-emms-playlist-load-playlist)
(define-key emms-playlist-mode-map "q" 'my-emms-playlist-destroy-playlist)
