Okay, I think I’ve finally cracked it. (But we’ll see what you all think first)

I’ve adjusted the wipe (very slightly) and I’ve smoothed the audio by adding a big drop off in volume once the scene has changed over, leaving quiet audio to slowly fade out to finish the musical phrase.

I’m hoping this resolves the issues of A) The music being too loud, B) The music being too long into the next scene, and, C) Allowing the musical phrase to complete. Because It checks all these boxes I think I’ve got it sorted, but before I release another version of the episode. I’ll check with everyone to make sure it’s fixed!
