If you haven't used a previous trial, Google is giving 60 days of all-you-can-listen to Chromebook users
Google Play Music All Access is pretty sweet. You can add any album to your library, listen to ad-free Internet Radio based on genre or based on a particular song, artist or album, or even try the "I'm Feeling Lucky" feature and see what you get. We all use it here around the office, and if it's available in your country, it's something you ought to at least take a look at.
If you have a Chromebook, looking just got easier.
Google is now givng away a 60-day trial of All Access when you sign up via your Chromebook. This offer doesn't extend to people who have already tried the service via another offer, or existing customers.
Spend your 60 days listening to classics, old favorites, or exploring new music. When the trial is up, you can extend and enroll in the service for $9.99 per month, charged via Google Wallet like any other app subscription. If you decide not to use it, just cancel and all is good. You won't know until you try!
