Looks kinda cool, like Tweetie for Last.fm, and introduces keyboard shortcuts for loving and banning. I’m not sure the previous version had that.
You don’t want this for scrobbling. There’s plenty of decent iTunes controllers that already do that well. You’ll want it for a decent way to get Last.fm Radio and recommendations on your desktop and to take a quick peak at what your friends are listening to.
Still needs a Heavy Rotation feature, so I can see at a glance what my friends are listening to a lot of lately. And walls. I need a way to share music posts to nobody in particular.
