Google debuted Google Ears at there I/O 2012 Conference last week. Google Ears is basically Shazaam or SoundHound, click on it and it will listen to the music and identify it. Once the music is identified, it will show the album artwork, the artist, the song title, and will give you the cost to buy the song in the Google play Store. This is a widget BTW.
If you get F/C’s try this guide:
1. Push the .apk to system/app
2. Fix permissions (rw-r–r–)
