I agree that the layout could use a lot of work. It's rather difficult to use on my X60 (1024x768 resolution).

Also, the filtering is very nice, but there's still a bit of information overload for me since there are over a hundred shows playing near where I live, in the genres I'm interested in, on a random saturday.

An extra feature that may be help alleviate that problem could be integration with some other site/service/application that already knows my musical tastes. For example, I've already spent a fair amount of time telling iTunes, Last.fm, pandora, and facebook what I like. It would be great if you could leverage that to provide me with a better filter.
