Last.fm claims the introduction of free music streaming on its music-focused social-networking service has boosted music sales among its partners.
The company launched its free service in January, and now claims that CD and download sales generated among its partners by use of its service climbed 119 percent as a result.
Last.fm says users have purchased 66 percent more albums and singles than they did before the company launched its on-demand music-streaming service.
"In just over two months it's become clear that people will buy CDs and downloads if they get access to the kind of service we offer," said Martin Stiksel, Last.fm co-founder. "No-one else can give music fans this amount of music for free - but more importantly also drive their discovery, as we do through our unique recommendation engine."
Stiksel said that the amount of time users spend on the site has also increased by 188 percent since January.
The company is offering users the chance to stream songs from a huge swathe of artists through Last.fm, reaching deals to offer this service with all the major labels and many independents. It provides links to purchase full tracks from iTunes, 7 Digital and Amazon.
