The new UI is nice.

But, there are two huge problems:
One, it requires logging in to Grooveshark now. This wouldn't be a deal breaker if it saved login details, but instead it asks every time it starts up, which makes it impossible to use in the car. And two, voice search no longer works properly, which was my favorite thing about Nineshark. So the new version is neat, but I'm reinstalling 0.0.2 now.
