Regarding your use case, it is almost impossible to do it in ONE job. Here is the explanation.

Let's make the following assumption. The duration of the video and song as follow.

input 1- intro.mp4 - 10 seconds
input 2 - content.mp4 - 10 seconds
input 3 - outro.mp4 - 10 seconds
song.mp3 - 30 seconds

You can use "external file" for audio for each input ( In theory, you can use "offset" to adjust the start time of the audio for input switch. i.e.

input 1- intro.mp4 - 10 seconds, audio start at 00:00:00
input 2 - content.mp4 - 10 seconds, audio start at 00:00:10
input 3 - outro.mp4 - 10 seconds, audio start at 00:00:20
song.mp3 - 30 seconds

However, because of the frequency of audio, it is almost impossible to make a seamless switch even using offset. Therefore, the most simple and perfect solution would be 1) create a job to merge all three videos, 2) create another job to merge the song to the output video of job1.
