Last.fm Launched Playground

Last.fm today announced about the launch a public version of it's playground site http://playground.last.fm/. Playground was a hidden website where employee showcased their weekend projects. But now it's no more hidden.

The projects at playground ranged from computing interesting stats or alternative recommendations to complex visualizations. However, many of the projects never made it onto the main site. Sometimes it was not clear where the project would fit, and sometimes it would have required some additional work to make it scalable or compatible with different browsers.

There are currently 3 demonstration projects available. multi tag search, artist name variations, and a weekly chart of the most frequent top 10 tracks.
