A good example would be the EchoWear app. This app has been designed for the Android Wear platform and it is basically the equivalent of Shazam or Soundhound for your wrist. For those who aren’t familiar with Shazam or Soundhound, it basically has the ability to listen to a snippet of a song and identify it for you.
EchoWear does the same thing and it uploads its findings to Gracenote who will then return the results on your smartwatch. The app can also be launched via voice command, thus making it even more convenient, so users will be able to quickly identify songs before it ends. The app was developed by XDA Recognized Developer, kevdliu, and for those interested in learning more, head on over to the XDA forums or the Google Play Store for the download.
