You should use the '==' operator with the locations, and add every locations as a different array under 'location':

register_field_group(array (
    'key' => 'songs_options',
    'title'      => 'songs options',
    'fields' => array (
        array (
            'key' => 'field_1',
            'label' => 'test title',
            'name' => 'test_field',
            'type' => 'text',
        ),
    ),
    'location' => array (
        array (
            array (
                'param' => 'post_type',
                'operator' => '==', 
                'value' => 'songs',
            ),
        ),
        array (
            array (
                'param' => 'post_type',
                'operator' => '==', 
                'value' => 'videos',
            ),
        ),
    ),
));
