Disable Facebook Comments Automatically On CPT

I ended up going with this type of solution. It seems to be working fine for me. I am open on ways to improve this code as it seems there is a better hook that could be used.

function on_music_publish( $post_ID, $post ) {
    if ( $post->post_type != 'music' ) {
        return;
    }
    update_post_meta($post_ID, '_disable_fbc', 'on' );
}
add_action(  'save_post',  'on_music_publish', 10, 2 );
