Google first featured its Google Now service in Jelly Bean. One of the Google Now sub-services is called What Is This Song. Just say its name in Google Now and you got it running. But what does it actually do?
What Is This Song is a cloud computing application and works much like applications such as Soundhound and Shazam. These kinds of applications listen to a bit of song that you play, and give you back many useful information about the Song, Album, Artist, Composer, the date it was composed, etc.
What is this song can also be installed on Android 2.2+..
