What happened?

Following Amazon.com's (AMZN -1.65%) launch of Music Unlimited last month, a new on-demand streaming service that is much broader than the previous Prime Music offering, the company has made good on its promise to launch a family plan. The price for a family plan is $15 per month and will include access for up to six family members, each of whom need a separate Amazon account in order to create personalized recommendations.

The individual plan includes a generous $2 per month discount for Prime members, which brings the monthly cost to $8. The family plan pricing for Prime members is less generous, and the only discount is $149 per year, which translates into two months free.

Does it matter?

Unlike Prime Music, which is a benefit that's included at no additional cost but more limited in scope, Music Unlimited is mostly a separate service that only receives discounts from having a Prime membership. Amazon is also forgoing its typical strategy of aggressively undercutting on price, as family plans from competing services Apple Music and Spotify are also $15 per month (those services do not offer discounts for annual subscriptions, though).

Amazon Music Unlimited doesn't appear to be particularly differentiated, and it's quite late to the market. It's hard to imagine the service garnering a large number of subscribers or moving the needle in any meaningful way for the e-commerce giant. In addition, the Music Unlimited discounts that a Prime membership gets are modest, so are unlikely to drive Prime membership adoption, either.
