I never removed and re-added my music folder in Groove but unchecked the folders read only properties, it did its thing, and remarked read only; but restarted the Groove program and started to add the music seemingly fine.
So I am guessing I will have to do the same thing for my Amazon and general PC music folders if the albums that I haven't moved from there are not listed
So starting to look like one issue down from this migration down.
Thanks for the folder properties suggestion.
