Random AudioClip by their names,Random Clip

Hi everyone I am new on Unity and I try to make simge audio manager I was watching brackeys tutorial and I managed to make my game just trying to add music anyway

  private void Awake()
     {
         foreach (Sound s in sounds)
         {
             s.source = gameObject.AddComponent<AudioSource>();
             s.source.clip = s.clip;
             s.source.volume = s.volume;
             s.source.pitch = s.pitch;
             s.source.playOnAwake = false;
         }
         FindObjectOfType<AudioManager>().Play("GameEntryMusic");
     }
     public void Play (string name)
     {
        Sound s = Array.Find(sounds, sound => sound.name == name);
         s.source.Play();
     }

I write a string name based find clip script , and It very usefull I can use it any script (FindObjectOfType().Play("GameEntryMusic");) like this however I have to make randomize it but I just couldnt figure that out. I have 4 clips name as succesful FindObjectOfType().Play("Success1"); Like this but I want them to play random any such as succes1,succes2,success3 like that. Any ideas ?
