Amazon Prime members will reportedly get a streaming music service this summer

Amazon(s amzn) will reportedly begin offering a library of streaming music to Prime members in June or July, but the selection will be limited and only include songs older than six months.

A new report in BuzzFeed corroborates leaks from April that Amazon is launching a streaming service to compete in an increasingly crowded field that also includes Spotify, Pandora(s P), Apple(s aapl), Google(s goog) and others.

BuzzFeed says Amazon’s offering will be packaged as an add-on intended to make its annual $99 Prime membership more attractive. (Prime also offers unlimited two-day shipping, streaming video and an ebook library.) The add-on appears to confirm my colleague Janko Roettgers’ assessment that digital music is “the thing you get when you buy something else.”

The report cites five unnamed music industry sources who confirmed that Amazon has reached licensing deals with two of the three major labels, Sony and Warner Music, as well as several independent labels. The sources also stated that the music companies would only be offering a limited selection of their archives, with content restricted to “songs and albums that are 6 months old and older.”
