How to add Label.Text to a List<> and have placed labels.text change to list index after event

Question

WHAT I HAVE:

This application places labels in a richtextbox and the labels text is = to the last button and radio button clicked/selected on the forum.

List<string> placed_transpose_btn = new List<string>();

    // Create Label at mouse click location with clicked chord's text.
    private void SongSheet_Click(object sender, EventArgs e)
    {
            Point mouse = PointToClient(MousePosition);
            SongSheet.SendToBack();
            placed_transpose_btn.Add(Current_Cord_Lbl1 + Current_Cord_Lbl2);
            this.Controls.Add(new Label
            {

                Location = new Point(mouse.X - 15, mouse.Y - 5),
                AutoSize = true,
                Text = Current_Cord_Lbl1 + Current_Cord_Lbl2,
                BackColor = System.Drawing.Color.White,
                ForeColor = System.Drawing.Color.Red,

            });

           // This is just to see the content of the list
            SongSheet.Text = Convert.ToString(placed_transpose_btn);

      }

OUTPUT:

System.Collections.Generic.List'1[System.String]

(Oh and labels only appear every 2nd click at last clicked location ... why is that?)

WHAT I NEED:

• Each label should be added to the placed_transpose_btn list.
• The list content should update according to a tab control on button press event (not attempted this yet as i need the first bit to work first :D )
• More questions may follow :s

Answer 1

Someone posted a answer but deleted it again.

He/She said

SongSheet.Text = Convert.ToString(placed_transpose_btn);

Is trying to convert the entire string. I should instead use

SongSheet.Text = string.Join(Environment.NewLine, placed_transpose_btn);

That said it means i have been adding the Labels to a list all along i was just not accessing it properly.
