Picked this spot for demonstration as it's easy to see for in game music being on and off. The criteria:

• From the Village, fast travel to Monastery.
• Walk to the middle of the silver platform and talk to the Monk.
• Cancel the conversation.
• Fast travel back to the Village as soon as possible (mashing F1 for the map)

At first glance, it appears the game is just loading the next area when using the time save. It's not- the game is straight up pausing the game while fading out the current track and not unpausing until finished fading in the next.

The Monk has a separate track playing that's different than the main monastery track. There shouldn't be a load here for just talking, but the gameplay still stops. Talking to him starts a fade out of the monastery track and fade in his one, then vice versa when stopping the conversation. Music off, it's instanteous.
