Most loading screens are effected by the UI Menu slider, Feel The Drop seems to not be. It's also SUPER loud.
Repro:
  1. Turn UI Menu volume to 0%
  2. Equip "Feel The Drop" loading screen.
  3. Swap to a world you don't already have cached
  4. Feel The Drop in your eardrums as they burst ;(
Unsure if this may be related to the issue where feel the drop plays multiple times: https://feedback.vrchat.com/open-beta/p/unity-6-1882-feel-the-drop-loading-screen-sometimes-plays-bgm-twice
However, even if it was playing 4x stacked or something, 4 x 0 should still be no audio.
