On my test environment, all the information from the ID3 tags show up just fine on the playlists using the core MediaElement.js player.
But on the live site, it doesn't.
Same plugins, same album, same theme just two separate WP installations on the same server, I searched around, but couldn't really figure out why.
They're both using
[playlist] shortcode in the template with the
<?php echo do_shortcode( '[playlist tracknumbers=true" artists="true"]' ); ?>
