Spotify today announced it is expanding Premium Duo, a feature that allows two people who live at the same place — say couples or flatmates — to share one subscription plan while maintaining their own individual accounts, to dozens of new markets.

Premium Duo is a remarkable concept from Spotify, which it first began testing in March last year and expanded to 19 markets months later. Starting Wednesday, Spotify Premium Duo is now available in 55 markets.

The new subscription offering is remarkable mostly because it’s solving a problem that very few people face today. At a glance, it appears that Premium Duo is designed to help people save money and gain access to a shared playlist that represents music they both cherish.

Two people can split the cost by joining Premium Duo, and it would save them a few bucks had they subscribed to the music streaming service individually. The problem is that if you are looking to save money, you can save even more by subscribing to Spotify’s family plan that supports six members in a group.

In the U.S., Premium Duo is priced at $12.99 a month. In India, it’s priced at Rs 149 a month ($2). (In India, subscriptions to Spotify, Apple Music, Apple TV+ and a vast range of services are more affordable generally.)

Spotify says it also creates a special Duo Mix playlist for participating members of a Premium Duo tier that will comprise songs both listeners like. But it offers a similar feature for members of the family plan as well.

I think I have figured out why Premium Duo exists. On its website, Spotify says that “with two separate accounts you can both enjoy your own music without having to take turns.” Couples, Spotify will really appreciate if both of you got your own paid accounts instead of listening to the streaming service from one account.

Alex Norström, who is Spotify’s “Chief Freemium Business Officer” said in a statement that the streaming giant was proud to launch Spotify Premium Duo. “With two individual Premium accounts, you can both listen independently, uninterrupted and get all of your personalized playlists and features tailored just for you. We are thrilled to bring this unique Spotify Premium plan to even more markets around the world.”
