The online music streaming platform is offering a new plan which includes two Premium subscriptions at a discounted price of €12.49 a month - compared to its usual cost of €9.99 per subscriber.
As reported by The Verge, the model will also include a new playlist called Duo Mix, which is generated automatically based on the listening habits of both users.
The plan - being tested in Colombia, Chile, Denmark, Ireland and Poland - will try to offer a good blend of both musical tastes, while there will also be 'Chill' and 'Upbeat' options to get songs of different tempos.
There will also be a feature for Shared Playlists.
In a similar manner to the Family subscription, the duo deal requires both users to live at the same address.
However, for this model Spotify will now ask the subscriber to provide the address as part of the Duo sign-up.
The existing Family plan lets up to six people share the same plan for €14.99 a month, but the company has become frustrated after sending out emails asking for subscribers to confirm home addresses due to friend sharing plans despite not living together.
