How to find all AudioClips in Resources folder and play them?

I have a problem: in my main menu I want to play random song from Resources folder, but it seems like I’m doing it wrong. Also I have public void “NextTrack()” to play next song. Can someone help me with this problem?
Here is the script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class music_main_menu : MonoBehaviour
{
    AudioSource audioSource;
    // Start is called before the first frame update
    void Start()
    {
        object[] audioList = Resources.FindObjectsOfTypeAll(typeof(AudioClip));
        Debug.Log(audioList);
    }
    public void NextTrack()
    {
        audioSource.Stop();
        audioSource.PlayDelayed(1f);
    }
}

No you can load the resources into an array, just do it sightly differently.

This link to unity docs shows how to load and reference a bunch of textures from the resources folder.

Adapt this code for audio clips and you should be fine.
