Amazon has just added Audible Channels, a subscription service that normally costs $4.95 a month, as the latest benefit that Prime Members get for free. Audible Channels is an audio collection of original programs, comedies, lectures, news, and articles that is consistently refreshed. The new Prime benefit also includes a rotating selection of more than 50 premium audiobooks that you can listen to for free. The audiobooks are arranged in categories like movies, which currently includes The Silver Linings Playbook and Slumdog Millionaire, or self-improvement books, like No Excuses! and Stitches, and many more categories. There is way too much content included with this new Prime benefit to list here. Once you install the Audible app, from Google Play or the Apple Appstore, you’ll be able to login with your Prime account and browse the complete collection of free content.
