TL;DR
Please add a check to the webhook for music tracks and add the artist summary to the track metadata if payload.Metadata.summary == “”;
Since Premium Music still doesn’t grab per track reviews/summaries, the webhooks feature is lacking a significant amount of info when it comes to music tracks unless you’re the type of person who manually adds reviews for every single song in your library…
My solution, to get more rich information from music webhooks, is to use the LastFM API to get the Artist summary from online - which is completely redundant since Plex has already scraped LastFM for this info.
