How to switch between 2 background songs in Unity: Survival Shooter?

Question

I've been futzing around with the survival shooter after the tutorial, and I added a damage chain score. I wanted to switch between the background songs once the damage chain gets high enough (from the original song to "Enter Sandman").

However, I ran into a problem: I couldn't attach the two audio sources to the background music component in the hierarchy without hiding the one of the audio sources.

I think the simplest way to explain the problem is to post my configuration and my code:

And here is my code (which, obviously, does not work right now--actually, it doesn't play anything at all...so it may be that the way I'm structuring the code is incorrect as well)...

 using UnityEngine;
 using System.Collections;

 public class SongManager : MonoBehaviour {
     AudioSource regular_music;
     AudioSource high_dmg_music;
     // Use this for initialization
     void Start () {
         regular_music = GetComponent<AudioSource> ();
         high_dmg_music = GetComponent<AudioSource> ();

         regular_music.loop = true;
         regular_music.Play ();

         high_dmg_music.loop = false;
         high_dmg_music.Stop ();
     }
     
     // Update is called once per frame
     void Update () {
         if (DamageManager.dmg_chain > 1500) {
             regular_music.loop = false;
             high_dmg_music.loop = true;
             high_dmg_music.Play ();
         } else {
             if (high_dmg_music.isPlaying) {
                 high_dmg_music.loop = false;
                 high_dmg_music.Stop ();
                 regular_music.loop = true;
                 regular_music.Play ();
             }
         }
     
     }
 }

How do I grab the correct audio sources and get the songs to toggle back and forth? (And any advice on how to make "Enter Sandman" play over the sound effects (and play louder) than the original background music would be huge too...since I want the player to be able to appreciate the atmosphere change, while they will be basically holding down the trigger (I made some changes to the spawn rate, firing speed, area of effect, etc, so there are a LOT of zombunnies and bears out there...)).

Try playing your sounds with just one AudioSource and switching between clips instead like this

 using UnityEngine;
 using System.Collections;
 
 public class SongManager : MonoBehaviour
 {
     public AudioClip regularAudioClip;
     public AudioClip highDamageAudioClip;
 
     private AudioSource audioSource;
 
     // Use this for initialization
     void Start ()
     {
         if ((regularAudioClip == null) || (highDamageAudioClip == null))
         {
             string error = "";
             if (regularAudioClip == null)
                 error = "The Regular Audio Clip has not been initialized in the inspector, please do this now. ";
             if (highDamageAudioClip == null)
                 error += "The High Damage Audio Clip has not been initialized in the inspector, please do this now. ";
             Debug.LogError(error);
         }
 
         audioSource = gameObject.GetComponent<AudioSource>();
         if (audioSource == null)
         {
             Debug.LogWarning("AudioSource component missing from this gameobject. Adding one.");
             audioSource = gameObject.AddComponent<AudioSource>();
         }
         PlayRegularAudioClip();
     }
     
     public void PlayRegularAudioClip()
     {
         audioSource.Stop();
         audioSource.loop = true;
         audioSource.PlayOneShot(regularAudioClip);
     }
     
     public void PlayHighDamageAudioClip()
     {
         audioSource.Stop();
         audioSource.loop = true;
         audioSource.PlayOneShot(highDamageAudioClip);
     }
 
     // Update is called once per frame
     void Update ()
     {
         if (DamageManager.dmg_chain > 1500)
         {
             PlayHighDamageAudioClip();
         }
         else
         {
             if (high_dmg_music.isPlaying)
             {
                 PlayRegularAudioClip();
             }
         }
     }
 }
