Why not use a listdlg instead? It allows you to create a cell array of strings (in your case song titles) which is then displayed in a dialog that the user can select from
strs = {'1. name of song', '2. name of song', '3. name of song'};
prmpt = 'Select songs from below list:';
[s,v] = listdlg('PromptString',prmpt,'SelectionMode','multi','ListString',strs);
Try the above and see what happens!
