After installing ios9 on my iPhone 5C, SIRI became incapable of identifying music (largely classical), to the point that I finally gave up trying. SIRI had been able to identify music, composers and symphonys on ios8. Installed ios 10 several days ago, and tried again. Nothing has improved. SIRI does not even try. Typical response is "I don't know that." Believe I will next explore how to delete SIRI from the iPhone.
