Test Animation w/Loud High Pitched Song

This is 1/4 speed, with the audio stacked with 1/4 speed but pitch corrected, half pitch corrected half resampled, and 1/4 speed resampled. The eventual video will be much longer. These slowed down versions are almost the right speed for the animation, but make the audio a challenge. I'm considering working with short sounds instead of songs. Then I can render them at 240 fps and 1/4 speed them down without any tweening, even go to 1/16 speed maybe.
