overflow scroll not working. I cannot scroll through my image

Hi, I have tested your code and here is the solution just remove
margin:auto from body i.e. from your css so that body’s css will look
like this

body {
    font-family: Futura;
    font-size: 2em;
    color: white;
    background: url(../img/BG_nowplaying.jpg);
    background-size: cover;
}
