Additional fields from Soundcloud

I am trying to get the plugin to grab the track tags from Soundcloud using the Music to Posts feature of this plugin, but it doesn't seem to be able to grab the tags. The API provides the tag list, but the script doesn't seem to ble able to read them, and the documentation is too general or outdated to tell me how I should proceed to get the tags from tracks. Example: This episode - https://soundcloud.com/meyerhaugen/employer-branding-og-merkevarebygging-med-cecilie-faye has several tags to this track, but neither seems to be added using the Auto Add Tags option in the advanced settings.
