I was trying to remember the name of Brahms' Hungarian Dance #5. Shazam failed as I sang it. Then I played the raw melody on piano in the right key, since I had found it elsewhere by persistence and luck. Shazam failed. Then I tried The Blue Danube as a test. It failed. Is Shazam just for pop music now? I have removed the app because there's only so much space on a smart phone. I want it for useful apps.
