OK.  I was wrong here.  The second expression should give t first.

I doubt whether aliases could be found via exec-path.

Anyway, how about this?

  (progn
    (setq emms-player-vlc-command-name
          "/Applications/VLC.app/Contents/MacOS/VLC")

    (emms-player-for '(*track* (type . file) (name . "foo.mp3")))
    )
