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{:});

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.
