Insert music track in between narration of audiobook

i’m going crazy!

I’m turning a manuscript into an audiobook. The author wants music tracks embedded in between section of the narration. None of it is uniform. First song after 26s then another in 10 mins. It’s supposed to be: narration - STOP - song - STOP - narration
In other words it’s not background music, it has its own stage.

As of right now i dont even know what tool to use. So i have a couple of questions:
Do i need to split the book into sections and treat them all as seperate tracks?
Is it possible to insert a music track while the narration is stopped and continue narration at the next point after the song?
How would you go about this?

There’s more than one way to skin a cat.
This is one way: copy and paste …
skincat1
[ Audacity preferences must have “Editing a clip can move other clips” enabled]

Here is another way …
skincat2

With either method paste/split at a zero crossing point to avoid clicks.
