How can I stop the graph , and how can it stip when the song stops?

function MusicPlay(InfoSongName)
PlayPlaySong = InfoSongName +".mp3";
[VariableSong, Variable] = audioread(PlayPlaySong);
Song = audioplayer(VariableSong, Variable);

PlaySong = input(' Will you like to play the song Yes or No ','s');
while strcmpi(PlaySong, 'Yes') ~= 1 && strcmpi(PlaySong, 'No') ~=1
    fprintf(' Selected Yes or No!!! \n')
    PlaySong = input(' Will you like to play the song Yes or No ','s');
end

%%

if strcmpi(PlaySong, "Yes")

%     NewVariable = audioread(PlayPlaySong);
%     plot(NewVariable)

%     soundsc(VariableSong, Variable);

    filename = PlayPlaySong;
    [Y,Fs] = audioread(filename);
    TotalTime = length(Y) ./Fs;
    t = 0:TotalTime/(length(Y)):TotalTime-TotalTime/length(Y);
    sound(Y,Fs)
    Y = Y';
    var = 50000;
    figure
    a = 1;
    for i = var:1000:length(Y(1, :))
        subplot(2,1,1);
        plot(t(a:i), Y(1,a:i));
        title("Left")
        subplot(2,1,2);
        plot(t(a:i), Y(2,a:i));
        title("Right")

        a = i;
%         fprintf("%f \n",a);
        pause(.75);
    end

    StopSong = input(' Would you like to stop the song? (Type Yes to stop or anything else to continue) ','s');

    while isempty(StopSong) || strcmpi(StopSong, 'Yes') ~= 1
        pause(12)

% It plays the song and the plots the grpah but it will not stop the
