You could easily attach handlers to the MouseEnter and MouseLeave events:

<Button Width="100" Height="50" Content="Click Me!"
        MouseEnter="Button_MouseEnter" MouseLeave="Button_MouseLeave" /> 

private void Button_MouseEnter(object sender, MouseEventArgs e)
{
    // start playing
}

private void Button_MouseLeave(object sender, MouseEventArgs e)
{
    // stop playing
}
