WP_Query no working when I use meta_query - php

Question

I am trying to make a query that will loop through a custom post type. admin can decide if any post will show or not in the backend. I used used advance custom field to make the admin backend option. My admin custom 'show_on_catalog_page'
here is my query :
$song_query_args_debug = array(
'post_type' => 'songs',
'post_status' => 'publish',
'posts_per_page' => 20,
'paged' => $paged,
'meta_query' => array(
array(
'key' => 'show_on_catalog_page',
'value' => 'show',
'compare' => 'LIKE',
),
),
);
And here is my response :

I have updated your code by below code, check it out now it should work with new wp_query,
$song_query_args_debug = array(
'post_type' => 'songs',
'post_status' => 'publish',
'posts_per_page' => 20,
'paged' => $paged,
'meta_query' => array(
array(
'key' => 'show_on_catalog_page',
'value' => 'show',
'compare' => '=',
),
),
);
