   projectdir = '/Users/Snorky/music';
   dirinfo = dir( fullfile(projectdir, '*.wav') );
   numfiles = length(dirinfo);
   order_to_play = randperm(numfiles);
   for K = 1 : numfiles
      thisfile = fullfile(projectdir, dirinfo(order_to_play(K)).name );
      play this file
   end

do i have to put this code in the callback function? because when i did so, this error came out when i click on the gui button.

Undefined function 'play' for input arguments of type 'char'.

Error in untitled1>play_Callback (line 180) play this file

Error in gui_mainfcn (line 95) feval(varargin{:});

Error in untitled1 (line 42) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)untitled1('play_Callback',hObject,eventdata,guidata(hObject))

I solved the random order part for you. You need to figure out how to play the file. There are multiple ways described in the MATLAB documentation.
