Google Ears, it is new to me but it was featured in the new Android 4.1 Jelly bean platform. Google ear, it works like a widget on your android homepage and allow you to know the names of songs quickly with audio input. Its functionality is very similar to Shazam and it works just like android widget. By recognizing the songs you have input, Google ears will direct you to the songs link inside Google Play Store, you can purchase the mp3 from the Google Play Store after the search. This is pretty cool feature and it works very well in any of the ICS ROM. Download it and try it out today.
