Social music site Last.fm has unveiled a new look: a slick new design, an iPhone app, a partnership with Logitech to stream music to compatible home stereo systems, and a host of new features.

With the new features, members can receive music recommendations instantly by naming a few bands and artists they like. Previously, they had to hook up their music libraries so that the site’s engine, or “scrobbler,” could read and analyze what songs they’d listened to recently. The site’s music charts now also update in near-real time.
