Its been a long time Google Play Sound Search came into Google Play Store but not for the United Kingdom users, which helps to search for a unknown song from your home screen and purchase from Google Play. Finally after almost a year Google Play Sound Search is now available for the users in UK
How Google Play Sound Search widget can help you recognize music and songs:
Identify songs, directly from your homescreen
Purchase identified songs straight from Google Play, and add them to your Play Music library
Keep a song identification history, synced across all of your Android devices, so you can purchase a song later
Add the widget directly to your lockscreen, so you can recognize songs even faster (for devices running Android 4.2)
After you’ve installed the Google Play Sound Search widget, go to the widget picker and drag the Sound Search widget onto your homescreen. Click on the widget to start recognizing.
As far we have come to know many of the users are not able to use the Google Play Sound Search but we were able to install it in our Nexus 4 and works very well, if you are not able to get in your device then you should wait for a while when it is available for everyone.
