While I think Skyward Sword's soundtrack is the best in the series, and that Breath of Wild's was the weakest, I will say they saved EVERYTHING for this piece of music, which doesn't just weave a bunch of themes together, but delivers it at 150%..

How many interlocking pieces of Zelda lietmotif can you count in this?
