Definitely has more stations than any other existing app on the market.
The interface is very simple, which I like, but it takes time to realise what means what. I mean like how the transfers are marked, etc. Maybe you could include some help with the app or starting overview.
And the only visual bug I've noticed on my Nexus One is that if the station name is too long, it goes under delete button and looks a bit messy. I think the button should have a white background, so that it hides text under it.
