Fresh off its world tour, Google Play Music is making it easier to store, shuffle and share your mobile tunes. For starters, Mountain View's music streaming-and-locker service now lets KitKat users with SD-equipped handsets put cached tracks on their removable storage. If you want to listen to your favorite band's songs out of order, Google has you covered there with a minor new feature that mixes an artist's All Access catalog into random playlists. What's more, there's a new option that lets you share songs, albums and acts via typical Android methods too. In our tests, however, non-GPM users get "album not found" error messages when they click through the links, our friends just may think this is a gift from Google -- guarding them from our incessant Katy Perry spam.
