When we got a look at the new Nexus 10 running Android 4.2 Jelly Bean, we expected Google's Music Explorer feature would slot into the Play store alongside the OS update. As it turns out, the feature has been quietly implemented, so you can now check out similar artists from within another's catalogue. We had a fiddle with it, but weren't particularly impressed -- you can only see three similar artists in the bubble-like UI at any one time, with no explanation of why they are linked together, or how the recommendations are decided. Some people will probably appreciate the casual browsing experience, but we found it a little too uninformative. Of course, you can make up your own mind by grabbing your tab and heading for the Play store. Just don't be surprised if the whole experience ends up bursting your bubble.
