(Pocket-lint) - Amazon is offering four months of free Amazon Music Unlimited streaming in both the US and UK.
After the four 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 70 million ad-free 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 $9.99/£9.99 a month (or $/£7.99 for Prime Members).
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.
