It's been a while since we first mentioned Sophia Teutschler's CoverSutra, a new iTunes interaction and manipulation app, and it's come quite a ways since its v1.0 debut. From the start it's offered things like global keyboard shortcuts for controlling iTunes (including one for toggling Shuffle), Apple Remote integration and album artwork that can live on your desktop underneath all your other windows (for that nice Exposé peek-a-boo effect), but recent developments have brought two major new features. The first is integration with the increasingly ubiquitous Growl notification system of which we're big fans, but the second big new feature finally made me decide to buy a license: integration with the Last.fm music community. For those who haven't seen it, Last.fm can watch what music you're playing (on both Mac OS X and Windows) and upload what is more or less a history of all the songs you listen to (it doesn't upload the songs themselves; it isn't the next Kazaa/LimeWire). From there you can share your playlists and discover new music through both friends and strangers who also use the site, and even embed your Last.fm playlist in a website or blog. It's a great service for any music enthusiast, and now it's built right into Sophia's excellent iTunes controller app. Consider me sold.
A demo of CoverSutra is available from CoverSutra.com, while a license sells for €9.95 or roughly $13 USD.
