Problems with music in Windows Forms in C#

Question

I am doing a job for college with Object Orientation and Windows Forms, but I have the following problem:

The program consists of several Forms, in the first I made the code to play music as shown in the code below

 private void Form1_Load(object sender, EventArgs e)
    {
        som = Path.Combine(CaminhoMusica, "MenuSom.mp3");
        WMPLib.WindowsMediaPlayer musica = new WMPLib.WindowsMediaPlayer();
        musica.URL = som;
        musica.controls.play();
        musica.settings.setMode("loop", true);
        guardar.Tocandomusica = true;
    }

however, when I open any other filters that have the Load event, such as this

 private void Habitos_Load(object sender, EventArgs e)
    {

        if (animal is Cachorro)
        {
            lbAnimal.Text = "Cachorro";
            lbClassificacao.Text = "Mamifero - Predador";
            pnMamiferos.Enabled = true;
            pnPredadores.Enabled = true;
        }
    }

at the end of the load event, the music stops playing in the entire program, and this is something that happens only in the Forms that have a load event, in the others the music continues playing normally, what I can do to solve this?

EDIT:Debugging the code, I realized that the problem is not in the load event but in

            Habitos habitos = new Habitos(x.Valor);
            this.Hide();
            habitos.ShowDialog();
            this.Show();

on the habitos line.Showdialog();,but I still don’t know what is causing this, because it is only in some specific Forms.

EDIT2: I solved the problem, I had to instantiate Wmplib.Windowsmediaplayer musica = new Wmplib.Windowsmediaplayer(); outside the Load event of the first form, because it seems to me that after opening a certain number of Forms, the load of the first one was finished and so the music object was deleted together
