Bug: Sound prefetch for Opening Crawl and Title Card

[KamiliaBlow]

Currently, the audio download happens while the animation is playing, which can disrupt timings (mainly affecting people with high ping >=100, but sometimes there are cases with low ping), causing the data transfer to take time).

How it works now:

bad.mp4

How it's supposed to work:

good.mp4

This happens from time to time. Especially noticeable on Opening Crawl, due to the fact that the original Star Wars intro music weighs several megabytes (2 mb), the delay of the background with music can take about 5 seconds.

P.S: Bad Batch theme weighs in at 800+ kb
