Microsoft is currently giving away four months of free Groove Music Pass with new subscriptions. That will include unlimited streaming of millions of songs, playlists, radio and more for 4 months.
To avail this new offer, you need to sign up for a Groove Music pass. Microsoft will then send you a promo code for an additional 3 months of pass, after the initial 30-day free trial is up. You will need credit card information to apply for the sign-up. You can cancel service anytime to avoid extra charges.
You can sign up and grab your free 4 months of Music Pass at Microsoft through December 31.
