Google Ears is a new music search feature part of the new Android 4.1 Jelly Bean improvements announced at Google I/O 2012 event last week. Google Ears is available in form an Android widget, it uses the tablet microphone to listen to music and try to identify it. Services like Shazam and SoundHound offers the same service with more functionnality (song tagging, sharing, history)
