Music playback based on MATLAB GUI dynamic music playback

function varargout = hdm_player(varargin)
% HDM_PLAYER MATLAB code for hdm_player.fig
%      HDM_PLAYER, by itself, creates a new HDM_PLAYER or raises the existing
%      singleton*.
%
%      H = HDM_PLAYER returns the handle to a new HDM_PLAYER or the handle to
%      the existing singleton*.
%
%      HDM_PLAYER('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in HDM_PLAYER.M with the given input arguments.
%
%      HDM_PLAYER('Property'.'Value',...). creates anew HDM_PLAYER or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before hdm_player_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to hdm_player_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one % instance to run (singleton)".
