Where's Britten? Mussorgsky? Vaughan Williams? Weill? Myaskovsky? Schnittke? Nielsen? To name but a few. I wouldn't complain (no, that's a lie), but Meyerbeer?!
I would agree with Al (even if Myaskovsky may be discussed).
Plus, I would add, without any doubt: Hummel, Janacek, Lalo, Max Bruch, Pergolese, Gerschwin.
And Clara Schumann, Berwald, Hornemann, Chausson, Holst and Carl Orff only if you think a very, very big list isn't a problem.
I would add a suggestion (not a demand as it requires some work...
): list them by century, at least. Or give their dates of birth and death.
And Josquin des Pres, not des "Prez".
