Shazam has been updated for Mac desktop so now you can detect some nice unknown songs directly from your Mac. Shazam app has long existed on iOS, Android and Windows Phone, having a fullscreen Windows 8 app.
Shazam for Mac has an automatic music detection in the backgroud, so if you activate this option it will automatically detect music coming from your TV or from your radio, triggering a notification each time it detects some new track.
If you don’t like the idea of something constantly listening to your activities, you can always disable the automatic monitoring. Or just close the app. Go to Apple’s Mac App Store and download the new Shazam for Mac.Source: theverge
