Google Play Music Unlimited is available on a four month free-trial to celebrate US Independence Day 2016.Google

To celebrate the Fourth of July, Google is giving away four months of Play Music Unlimited and YouTube Red for US subscribers. Users are reporting that the offer is only available to new subscribers, however some with expired free-trials have managed to take advantage of the saving.

At roughly $10 (£7.54) a month, the promotion designed to celebrate US Independence Day represents a total saving of $40, although due to the theme the offer is unlikely to stick around for too long.

For those looking to take advantage of the offer, all you need to do is go to the Google Play website or access the Play Music app on iOS or Android and sign-up for the trial. Here, you can find a direct link to the offer on desktop.

Users must create a Google account or sign into an existing one to purchase the free-trial. After the four months of free content has expired the subscription automatically continues and adjusts to the standard rate of $9.99, although as the terms and conditions note: "You may cancel at any time before your trial end date and still receive the full 4-months of membership benefits without incurring further charges."

Play Music Unlimited is Google's Apple Music/Spotify/Tidal-rivalling music streaming service and gives subscribers access to a library of over 35 million tracks. Play Music also allows subscribers and free users to upload up to 50,000 of their own songs to its cloud storage platform for streaming access across multiple compatible devices.

YouTube Red meanwhile lets subscribers enjoy YouTube videos entirely ad-free and allows for background playback and offline viewing. The service also provides access to exclusive video content from some of YouTube's most popular luminaries such as PewDiePie and College Humour.

First-time UK subscribers can still get the usual one month free-trial of Play Music Unlimited, however YouTube Red is currently only available in Australia, New Zealand, and the United States.
