Catalina Stuff

I've said previously that the AppleScript scripting definitions for the Music and TV apps are pretty much lifted from iTunes. However, there are differences.

For example, a script that targets composer of a TV track will fail. Because TV doesn't use the Composer tag. Or the Album Artist tag. Or the artist property. Instead of artist, TV has a director property. And a Music track doesn't understand show, season number or episode ID; a TV track won't grok movement or work properties.

Stuff like that makes it difficult to write one script that can work in both Music and TV without doubling-up some of the code. Or adding some extra conditional tests. I'm not complaining; it is what it is, to be simply trite about it.

When analyzing the pasteboard in a drag operation from the Music app, the dragging pasteboard types include “com.apple.tv.metadata”, but one would expect there to be “com.apple.music.metadata” type in place of—if not in addition to—the “tv.metadata” type. ¯\_(ツ)_/¯

There is definitely an Artwork Issue. Files that I have downloaded from the cloud do not contain image metadata, but the artwork is certainly downloaded into the Music database because I can see it throughout my library. I just don't see the artwork being transferred to the files at all. The files do not have "Get Info" artwork and the artwork does not appear in a Quick Look panel. However, artwork appears as expected for files that have always been local.

Files downloaded from the cloud also do not contain purchaser metadata. Not sure what that's about.

The previous two metadata issues may be related.

I still don't know what's causing the Invalid parameter error people are seeing with launching scripts. As far as I can tell, the issue "goes away" after a short time.

Frankly, there's so much stuff going on when you first launch anything in Catalina (with permissions and warnings and threatening security dialogs and other whatnots) that it just may be a minor system glitch.
