A cryptic message written by Googler Stephen Lau on his Google+ page hints at an announcement coming soon. In addition, a video made by Google shows producer Young Guru wearing Google Glass and using the Shazam like app to find out the name of a song playing at a restaurant. Later on, he starts listening to the song using Glass. Earlier in the video, we see the producer grab for the stereo earbuds.
While only Google's music service will initially be available on Glass, eventually third party apps are expected to offer competing music products. The report says that Google will market the music service on Google Glass as easier to use than a smartphone with the voice command and easy to view screen keeping music listeners from having to look down at their handsets all day.
