URL prefix for posts WordPress

Question

So I have website on a WordPress engine. And I want to make posts urls looks like http://website.com/blog/post-name/ or http://website.com/blog/categ-name/post-name/. But everything else will look like http://website.com/page-name/. Just want to add prefix 'blog' to urls for all posts but not pages. My permalink settings is /%postname%/. If i will put /blog/%postname%/ I will have 'blog' prefix in every URL of my site :( I can't find solution in WordPress admin backend and I didn't find any acceptable plugin for this. Any help is appreciated, thanks.

I did this:

add_action( 'init', 'redefine_post', 1 );
function redefine_post() {
    register_post_type( 'post', array(
        'labels' => array(
            'name_admin_bar' => _x( 'Post', 'add new on admin bar' ),
        ),
        'public'  => true,
        '_builtin' => false,
        '_edit_link' => 'post.php?post=%d',
        'capability_type' => 'post',
        'map_meta_cap' => true,
        'hierarchical' => false,
        'rewrite' => array( 'slug' => 'blog' ),
        'query_var' => false,
        'has_archive' => true,
        'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'trackbacks', 'custom-fields', 'comments', 'revisions', 'post-formats' ),
    ) );
}

It involves creating a custom post type (which is slightly annoying), but it overrides and works with post.

I wish there was a better way of doing this! (Otherwise yes you get /blog/ in front of everything if you just change the permalinks).
