It was difficult for me to decide, but as amazing as the animation is (even today), the music is incredibly nostalgic, and I can't imagine this movie with a different soundtrack.

Don't like the animation, it's way too dark, dull and looks like an incomplete animation. Not a huge fan of the music too, but at least it's better compared with its animation.

Hard to pick, I love them both very much, but the animation is so impressive even today nearly 80 years later, the music is also amazing, love all the songs and the score is fantastic too
