Had time to whip up an example. I didn’t stay on the same path, but it’ll give you another route to consider (cleaner IMO). See the updated answer.
Now, you’re probably going to notice unwanted behavior. You have to wait… before you can transition. You could gain a little more time by fading out the UI and shortening up the Fade Out. At the end of the day it’ll need to be quick/responsive. One thing you could look into is Level Streaming, where the audio can be handled on the persistent level.
