The $29 app which took Last.fm and integrated it with iTunes on your desktop has now gone open source.
SweetFM switches seamlessly between Last.fm and iTunes. Tune to any station and you can control Last.fm with SweetFM’s interface – stop the stream and you can use it as an iTunes controller!
Nothing was said about this switch but I suppose it’s because of the conflict they had with Last.fm which has seemingly forced them to go Open Source. In any case, it’s a really good app for Last.fm users. Download here.
