If you regularly go out wearing Google Glass, you've probably lamented the lack of major music app choices. There's Play Music and... well, that's about it. Never fear, though, as Pandora has just released a Glass app for its internet radio service. The wearable-ready software lets you control streaming without ever having to reach for your phone; you can create or choose stations solely using your voice, and the touchpad lets you both skip annoying tunes and give the thumbs-up to songs you like. It won't cost you anything to download the app, although you can't really call this free. Besides the $1,500 Glass itself, you'll likely want to buy Glass-specific stereo headphones -- that's a lot of money just to get internet radio on an eyepiece.
