Australia's best song

Charts of anything (by the way, quite recently the same magazine came up with a new idea and Pink Floyd's Brain Damage won the "Best song about going crazy" poll) are always treacherous, because there is practically no universal arbiter who remains completely impartial. Everyone is influenced by their age (in other words, the time they grew up listening to music), the place where they live (American society perceives a number of compositions in a historical context that is completely different in Europe or other countries), but also by personal preferences. How can anyone compare five hundred albums (or any amount of anything) without hearing all of them on the list?
