How do i repeat an audio file?

I am running a song through a while loop but once the song has finished its interval it doesn't keep repeating itself. Any help would be much appreciated!

a = true;
while(a == true)
    play(song1)        
end

If song1 is an audioplayer object, then you can

while true
    playblocking(song1);
end

But another approach with audioplayer objects would be to use

song1.StopFcn = @(src, event) play(src);
play(song1)

Just use repmat to repeat the audiofile :)
