The Android world's been a-buzz this last week over a few new Android Market URLS, including http://market.android.com/music/ and http://market.android.com/movies/. In case you thought there was nothing to this tip, guess again: the third member of this trifecta (http://market.android.com/books/) has gone live. That's right, visitors to the Android Market can pick up Glenn Beck's mile-a-minute thrill ride The Overton Window for a mere $9. We hope that takes some of the sting out of the fact that a Google Music launch wasn't part of this month's Honeycomb event -- although if we had to wager a guess, we'd say that the company will have Music and Movie offerings soon enough.
