@psychoadept and frankz...
Good point about having the featured/guest artist as I currently have it (in the title) in addition to specifying as a guest artist in the splitter. Searching will definitely become more accurate.
As I said in boroda's thread (https://getmusicbee.com/forum/index.php?topic=3833.msg171126#msg171126
) the preset isn't setting the guest artist tag. Nor is it removing the featured/guest artist from the title. Which now is a good thing, so I need to update that comment before boroda wakes up and reads it.
Thank you both.
