... the security implications?
``If the mic wasn't left on, it would take the app longer to both initialize the mic and then start buffering audio, and this is more likely to result in a poor user experience where users 'miss out' on a song they were trying to identify.''
What if they'd actually turned off the microphone instead of fooling the end-user into thinking it was off. And, then, if user's complained about missing the first 0.25s (or whatever) of the tune, Shazam responded to the users that there was a slight delay but that it was necessary to protect them from potentially being eavesdropped on? How many users would have found that reasonable and been fine with that? Well, we'll never know because Shazam didn't, apparently, care too much about the end user's privacy. But making sure they could identify an effin' song? Well, that's of paramount importance!
