Question

I have the following code in Draw() in Game1. However, the Music only plays when I’m pressing the close button for the program. Where should I be putting MediaPlayer.Play() if not there? normS, fastS, slowS, and playing are all Song types. If you need me to clear anything up, just ask.

        if (stateS == "normal")
        {
            if (!MediaPlayer.Equals(playing, normS))
            {
                playing = normS;
            }

            spriteBatch.Draw(norm, pos, Color.White);
        }
        else if (stateS == "fast")
        {
            if (!MediaPlayer.Equals(playing, fastS))
            {
                playing = fastS;
            }
            spriteBatch.Draw(fast, pos, Color.White);
        }
        else if (stateS == "slow")
        {
            if (!MediaPlayer.Equals(playing, slowS))
            {
                playing = slowS;
            }
            spriteBatch.Draw(slow, pos, Color.White);
        }
        MediaPlayer.Play(playing);

Answer 1

Is there a particular reason why you need to have the songs play out of the Draw method? Draw should be reserved for drawing things.

Like user1306322 said in the comment above, I would recommend moving the

MediaPlayer.Play(playing); 

into the Update method, and wrap it in a conditional (so you dont just keep playing a new song every update, which I think is what is happening for you now since clicking and holding the Close Window x stops the updates. You could try this by dragging the window around as well):

if (!MediaPlayer.IsPlaying)
{
    MediaPlayer.Play(playing);
}

If necessary, you can leave the rest of the code in Draw, but most likely this whole thing should go in Update.

edit I just realised you may not have a conditional on this because you want to be able to change the song at any time. In that case, you should set a variable to hold your “Last Song”, so you can compare it in your conditional like this:

if (MediaPlayer.IsPlaying == false || playing != lastPlaying)
{
    MediaPlayer.Play(playing);
}
