n = randi([1 n]);
for i = 1:n
    randCD = randi([1 3]);
    randTrack = randi([1 c(randCD)]);
    fprintf('CD %d Track %d\n', randCD, randTrack);
    if randCD == cd && randTrack == track

From my understanding you want to play songs from user chose cd and track.

Inorder to achieve the above requirement create a array with list of all songs and ask user to select one track from available track

As an example

cd1=['song11.mp3','song12.mp3','song13.mp3'];
cd2=['song21.mp3','song22.mp3','song23.mp3'];
cd3=['song31.mp3','song32.mp3','song33.mp3'];
% display available options
fprintf('\nThere are %d tracks on CD 1\n', length(cd1));
...
% ask user to select one cd
cd = input('Please enter the number of the CD: ', 's');
%validate his choice avaialble or not
%ask user to select track and validate the track available
track = input('Please enter the track number: ', 's');
%play the selected song using audioplayer object
[test, fs]= audioread(cd1[track]); % place selected cd and track cdselected[track]
s=audioplayer(test,fs);
