Question How to correctly set music listen button of spesific clicked object?

Hello guys! I have a problem with making "play and stop button" for listening to music. I want to play music of a specific object, on the first click it should play and on the second click stop. But the problem is I can stop music only when touched any part of the screen except listen button(coz' I used "Input.GetMouseButtonDown(0)" ), It should stop when the same button is clicked a second time, but it replay the music.

Code (CSharp):

1.  
2. private void Update()
3.     {
4.         if (Input.GetMouseButtonDown(0))
5.         {
6.             Listen_IconActive.SetActive(false);
7.             SongPlayer.Instance.StopBeat();
8.         }
9.     }
10.  
11.     [System.Obsolete]
12.     public void OnListenClicked()
13.     {
14.         SongPlayer.Instance.LoadBit(Model.name);
15.         Listen_IconActive.SetActive(true);
16.         SongPlayer.Instance.PlayBeat(0f);
17.         if (!File.Exists(Path.Combine(Application.persistentDataPath, GameConstanst.SHORT_BEAT_PATH_RESOURCE, Model.name + ".mp3")))
18.         {
19.             Debug.Log("sacrifice 1");
20.             StartCoroutine(GetMP3(Model.short_beat_url, GameConstanst.SHORT_BEAT_PATH_RESOURCE, Model.name, true));
21.             Listen_IconActive.SetActive(true);
22.             SongPlayer.Instance.PlayBeat(0f);
23.         }
24.     }
25.  
26. Any help would be much appreciated!
