UI Text to Display Loading Progress of Songs in Music Folder

OK I have this music player scrip that basically all that is missing is a way for it to display the progress of the songs being loaded so that the player does not think its broken while nothing is happening. How can I do this with the existing UI text that also displays the song currently being played?

Or would I need a totally different UI text reference?

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 using System.IO;
 using System.Linq;
 using UnityEngine.UI;
 
 public class AltMusicPlayer : MonoBehaviour
 {
 
     public Text MusicListText;// Reference to my UI Display Text for Songs
     private string display = "";//UI Text reference
     public enum SeekDirection { Forward, Backward }
     
     public AudioSource source;
 
     bool playing = true;
 
     public List<AudioClip> clips = new List<AudioClip>();
     
     [SerializeField] [HideInInspector] private int currentIndex = 0;
     
     private FileInfo[] soundFiles;
     private List<string> validExtensions = new List<string> { ".ogg", ".wav" }; // Don't forget the "." i.e. "ogg" won't work - cause Path.GetExtension(filePath) will return .ext, not just ext.
     private string absolutePath = "./Audio/Music"; // relative path to where the app is running - change this to "./music" in your case
 
     void Start()
     {
         //being able to test in unity
         if (Application.isEditor)
             absolutePath = "Assets/Audio/Music";
         
         if (source == null)
             source = gameObject.AddComponent<AudioSource> ();
         ReloadSounds ();
     }
     
 
     void Update(){
         if(!source.isPlaying && playing)
         {
             Seek(SeekDirection.Forward);
             PlayCurrent();
         }
     }
