I don't like the simple, all text interface. I think an app like this needs a clean but graphical interface. Take a look at this screenshot: http://skitch.com/rksprst/3t9q/the-perceptron-astute-music-r...

Am I supposed to understand any of the text there? It looks like a bunch of random works thrown together. No human will ever read that. No offense but this display reminds me of those "crack/serial" search engines that just list a bunch of random programs in alphabetical order just for seo.

I think you have a neat idea. But please get a designer.
