Indeed, you can tell very clearly when they're singing one winged angel. Except that also brings to light the whole Aerith/Aeris issue. See... "Aerith" is supposed to be pronounced like "Aeris". Well Sephiroth... its supposed to sound like Sephiroth... apparently. Bah, forget it. I don't want to get into it when I already know the answers XD I just find it ironic that the argument bends around backwards when talking about someone else. But I guess that's because she's supposedly a reference to "Earth" so it works the same in the end.
