I like the idea behind `emms-select-playlist-track'. But I can see
renaming it to something like `emms-play-playlist-track' because it
actually plays the track.

However, I would change it so it doesn't create yet another copy of the
playlist as a hash-table which now needs to be kept synchronized. The
playlist-mode buffer is already a data structure and it's unclear how
long the playlist would need to be in this case in order to be slower
than a hash-table.

I don't know why `when-let' or `subr-x' would be an issue. As long as
they are available on all recent versions of Emacs I don't see a
problem.
