Accessing widget information

It seems that the index value goes incrementing and we add/remove instances of the widget.

To make sure the correct data is grabbed, I can only think of checking inside the widget data itself through some control variable, something like:

Array ( 
    [2] => Array ( 
        Accessing widget information => asian kung-fu generation 
        Accessing widget information => awesome band 
        [var-of-control] => true (or some other convention) 
    ) 
    [_multiwidget] => 1 
)

Or even by title. The following function does this checking:

add_filter( 'the_content', function(){
    $res = get_option( 'widget_my_widget' );
    $check = check_array_key_value( $res, 'title', 'asian kung-fu generation' );
    print_r( $check );
});

function check_array_key_value( $array, $key, $val ) 
{
    foreach ( $array as $item )
    {       
        if ( isset( $item[$key] ) && $item[$key] == $val)
            return $item;
    }
    return false;
}
