(Pocket-lint) - Amazon is offering three months of free Amazon Music Unlimited streaming in both the US and UK at the moment. But you'll need to sign up over the next few days as the offer is only on until 11 January 2021. 

After the three months expire you'll be switched onto a full plan costing $7.99/£7.99 a month for Amazon Prime members, so you'll need to cancel before the free trial is up if you want to avoid being charged. 

This offer is available only to new subscribers to Amazon Music Unlimited so if you've previously had a trial then unfortunately you won't be able to take part.

Amazon Music Unlimited offers over 50 million HD songs to stream on multiple devices, including the company's own Echo speakers. Naturally, you can also download tracks to listen to offline on smartphones or tablets.

There's also Amazon Music HD - a premium service that costs more than the standard version of Amazon Music at $14.99/£12.99 a month. 

And as with other streaming music services, there's also a $14.99/£14.99 a month option for a family plan that covers up to six family members, all of whom can stream music on all the different devices that they choose.
