After it failed to get Ritchie Blackmore, and gave up, it gave me a list of ten probables. Not on the list either. It then asked me to submit who it was, which I did.
I guess it's still learning.
Plus, I tried not to answer with any "Don't know"s or "Probably"s, but, I also may have answered incorrectly, based on what I thought I remembered about him. Although, I had him up on google to try and be as accurate as I could. In this case (if that's the case), it may have guessed my choice sooner based on a few "Don't know"s and such...
