Continuing Saga of the iTunes Genius Sidebar FAIL

I know I have taste in music that runs outside the mainstream, but seriously...what's going on at iTunes? Why is it that when my selection is "Il segreto per esser felice" from Donizetti's Lucrezia Borgia sung by Marilyn Horne that the iTunes "Genius" recommendation is "Con te partiro" as "sung" by Andrea Boccelli? This would be like me going into a restaurant and remarking that I like Veuve Clicquot and having the sommelier respond by suggesting a glass of Diet Pepsi. WTF, people?
