So, i want play music all time. when the scene is reloaded, the music starts from the beginning, but I want it to continue from the same moment using UnityEngine;
public class MusicBack : MonoBehaviour
{
private void Awake()
{
GameObject[] objs = GameObject.FindGameObjectsWithTag("Music");
if (objs.Length > 1)
{
Destroy(gameObject);
}
DontDestroyOnLoad(gameObject);
Debug.Log("correct");
}
}

I think that you'll need a custom script, like suggested here: https://answers.unity.com/questions/1260393/make-music-continue-playing-through-scenes.html
The idea with that answer is to use DontDestroyOnLoad to keep the audio source the same throughout scenes. So if you move from Scene 1 to Scene 2, the audiosource is still Scene 1's, if I interpreted taht correctly. Then there's just some logic for not playing the audio in scenes where it shouldn't be played.
Probably this could have been found with a quick google search though.
