I think by now we are all used to the Windows startup sound and you could probably pinpoint it no matter how crappy the speakers were that it was playing out of. Microsoft might be changing things up a little bit by providing a new more “spiritual” startup sound in Windows Vista.

It is much more subtle than the normal Windows sound and I actually like it. You can definitely recognize that they tried to keep it close to the old sound while giving it a fresh new appeal.
If you still don’t like it don’t worry, you can always disable it!
