Media Player & Metatags

I have created a series of scripts that play locally hosted aac files (m4a) and cast them to a statically defined google home speaker. I can choose various ambient sounds or shuffle playback of some of my favorite bands discographies. Within my script I have manually added metadata and artwork and am using the mini-media-player to show what’s playing. One thing I just cannot figure out is how to read the metadata tags from my local files and pass that into my script prior to playback. Has anyone out there been able to figure this out? Even with the media browser component, it browses and plays all my files beautifully, but doesn’t reflect the embedded metadata. Thoughts?
