Import iTunes JSON into WordPress

I am working on a little project that parses the JSON feeds of iTunes and imports the categories into WordPress. Here’s the relevant snippet.

I am using wp_remote_get here, a much simpler alternative to using CURL or file_get_content() of PHP. WordPress has built-in functions for inserting categories – wp_insert_category and wp_create_category – but they aren’t working in 3.5.1 and hence had to use wp_insert_term.
