Wordpress: looping though custom post types and only return results in a given taxonomy

I am creating a wordpress theme for a record label. One aspect is the video gallery.

I created the gallery using a custom post type called 'videos'. The code below is what I placed in my functions.php file to set up the post type:

add_action( 'init', 'create_my_post_types' );
        function create_my_post_types() {

register_post_type( 'videos',
        array(
            'labels' => array(
                'name' => __( 'Videos' ),
                'singular_name' => __( 'Video' ),
                'add_new' => 'Add New Video',
                'edit' => 'Edit Video'
            ),
            'public' => true,
            'exclude_from_search' => false,
            'supports' => array( 'title', 'editor', 'thumbnail','page-attributes','excerpt' ),
            'rewrite' => array( 'slug' => 'videos', 'with_front' => false ),

        ));
    }

I also created a custom taxonomy called 'artists' so I can assign the artist name to each video I upload.

 add_action( 'init', 'create_videos_taxonomies' );

    function create_videos_taxonomies() {

        register_taxonomy(
            'artist',
            'videos',
            array( 
                    'hierarchical' => false,
                    'label' => 'Artist',
                    'query_var' => true,
                    'show_tagcloud' => true,
                    'show_ui' => true,
                    'rewrite'=>array('slug' => 'artists', 'with_front' => false)
                  )
            );
        }

At this point, everything works fine on the backend and the video page returns all of the videos successfully.

On another area of my website, I have pages for every single artist. On any one of these artist pages, i would like to be able to loop through all of the videos in the custom post type I created, and only return results in a given taxonomy. Below is my code to loop through a custom post type:

<?php $loop = new WP_Query( array( 'post_type' => 'videos', 'post_child' => 0, 'posts_per_page' => 5 ) ); ?>
    <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php the_post_thumbnail( 'video' ); ?>
<?php the_content(); ?> 
<?php endwhile; ?>

This successfully loops through the videos, and returns the 5 most recent. I need this to loop through all the videos with a specific taxonomy slug or ID. For instance, I created a taxonomy called 'Smash Palace' and it has a slug of 'smash-palace' and an id of '17'. Any idea how I can loop though this custom post type and only return results in a given taxonomy?

I feel like you should be able to query based on post_type and taxonomy like this:

<?php $loop = new WP_Query( array( 'post_type' => 'videos', 'taxonomy_name' => $term, 'post_child' => 0, 'posts_per_page' => 5 ) ); ?>
