Adding what colleagues commented on your question would look like this: 

$minha_variavel = get_post_meta($post->ID, 'mp3'); // O terceiro parâmetro é FALSE por padrão

foreach ($minha_variavel as $arquivo) { // Segundo a documentação o retorno é sempre um array
    echo wp_get_attachment_url($arquivo);
}
