Just tested that with a interactive function but for some reason I need
2 kill-line or else it adds a empty line after the entry:
(defun emms-ephemeral-title ()
(interactive)
(let ((track (emms-playlist-track-at (point))))
(emms-track-set track 'info-title "TEST")
(emms-with-inhibit-read-only-t
(kill-line)
(kill-line)
(emms-playlist-insert-track track))))
Now I have to find out how to do that outside of the buffer in a
non-interactive way. I think I need "with-temp-buffer" but that is for
another day but yes it works on prinziple. Any idea why I need 2
kill-line here?
