Millions of fringsters will now be able to launch fring’s specially mobile-optimized version of Last.fm inside the fring client, enabling them to tune and listen to streamed music radio channels, including their own Last.fm library, tag favorites or ban disliked tracks, view album artwork and take their Last.fm music account mobile.

Fring mash it’s existing social and communication capabilities into the Last.fm social music experience; friends are able to view in real-time what each other are currently listening to, via a dynamic, media-rich friends list embedded into the Last.fm add-on.

They can share the music experience together and connect with each other via fring’s inherent communication services such as instant messaging chat via Skype, MSN Messenger, GTalk, Yahoo!, AIM and ICQ, from inside the Last.fm add-on experience.

“It represents the next stage in fring’s planned evolution – a centre of gravity shift from simply aggregating and providing mobile internet communication tools, towards providing a platform for friends to enjoy rich and dynamic mobile experiences together, with tools such as voice and instant messaging being just one part of the story.” said Avi Shechter, fring co-founder & CEO.

Fring’s API, released last year and available at http://developers.fring.com, provides the tools for any third party developer to create an add-on of its own. The Last.fm add-on is the newest in a range of fring Experience projects currently in development
