What about using "d" (i.e. the "describe" mnemonic instead of the "info"
mnemonic)?

> +  (sort (append '("Bitrate" "Duration" "File" "Format") (mpc-cmd-tagtypes)))
> +  "Tag types available for use in `mpc-song-viewer-tags'.")

Hmm... running `mpc-cmd-tagtypes` when we load the file seems risky: we
may not know the `mpc-host` yet, or any other thing may go wrong.

> +(defun mpc-describe-song (&optional file)

Any reason we can't make the argument mandatory?

This should bind `inhibit-read-only` instead.

Why use `select-window + display-buffer` instead of `pop-to-buffer`?
