Things are busying up again at Last.fm, with the launch of a new HTML5 web app this morning called Last.fm Discover. The idea: it will help people discover songs from the company’s catalogue of three million tracks from independent artists, “from Newgrass to Indietronica”. Last.fm has worked with design agency Somethin’ Else and Microsoft – which is also on board as a sponsor – on the new site, which takes the form of an ad-free streaming radio channel. Users get unlimited track skips and listens, and can compile their own ‘mini mixtapes’ to share with friends on social networks. Tracks will also be downloadable from the service, according to Last.fm. “Our team has grappled over the years on how to best overcome the barriers of discovering new music, whether it be finding new artists from around the globe, downloading tracks or sharing with friends. Last.fm Discover solves this problem,” says VP of product Matthew Hawn.
