To sell Glass, its augmented-reality form of eyewear, Google has already tried to make it a fashion accessory and a must-have video device for any parent or sky diver. Now it is also presenting this $1,500 piece of wearable technology as a way to interact with music. On Tuesday, Google will unveil a set of features for Glass to search for songs, scan through saved playlists and listen to music in high fidelity. This can all be done while a user is wearing the lensless frames, which respond to vocal commands and have a small computer and transparent projection screen above the right eye. When Glass boots up, it will display “listen to” among its standard voice commands — like “take a picture” and search for a term on Google — and let a wearer name a song or artist and then stream that music through Play, Google’s media and apps hub.
