What with Google I/O being this week, there are naturally some wonderful additions to Android's app family from the mothership herself. But that doesn't mean third party developers have just been sitting around twiddling their thumbs—this week's set of apps has offerings from everyone.

Google Hangouts: After taking some major steps forward earlier this week with the announcement that Google Talk support would finally be hitting Outlook, the long-anticipated Babel all-in-one chat service has finally been revealed as... Hangouts. Which yes, we already have sort of—but not like this. [Free]

Google Play Music: Google's rumored Spotify competitor is real, and it's called All-Access. As soon as you start using it, it starts learning your preferences. You have access to everything in the play store. You pick a song, and can instantly create a station based on it, a la Pandora, but with much more control. You'll see the whole playlist ahead of you. You can swipe away tracks you don't want to hear, and you can re-order them at will. [Free]

Festival Ready: Summer approacheth, and with summer comes festivals—all sorts of festivals! Whether you're a music buff, renaissance enthusiast, or food and wine connoisseur there's a festival out there somewhere waiting for you. Now an actual Swiss Army knife is handy to have, but probably won't do you too much good at any of the above. A festival-specific Swiss Armyapp though? Just what ye olde doctor ordered. [Free]

Kicksend: It's easy use your phone to share just one photo or video to a friend, but what about an entire set? Kicksend lets you send large batches of photos and videos to your friends in one fell swoop. It's been on Android for a while, but it's newest update gives the service one very welcome, major new feature: home delivery. Pick photos off your phone and they'll be shipped off in real, physical form to any doorstep of your choosing. [Free]
