There's nothing "mysterious" about making queries in search engines.
You make a query, i.e. you enter some criteria, and get results.
If the criteria you entered are relevant, you'll get proper results. Even if not exactly relevant, but close enough.
But, if the criteria you entered are wrong, then you'll surely get irrelevant information.
In my case, all these music files are always properly tagged (Album, Artist, Genre, Year, everything).
Therefore the criteria for the search should be ok (the bio is always correct). But still I frequently get irrelevant Artist photos, and in some cases totally irrelevant.
I've tried myself all possible queries I could think in various search engines, and these irrelevant photos are never displayed.
SInce, MB doesn't have any preferences regarding Artist Biography photos retrieval, (apart from defining the location of C:\Users\user\Music\MusicBee\Artist Pictures\Thumb)
I want to understand how these queries are made, so, maybe it's something that could be avoided, maybe by some tag modifying?
And maybe, if Steven could allow configuring the Artist Photos search queries in Preferences, to customize them making them as specific as I want.
