Has anybody tried Goombah yet? What the heck is Goombah, you ask? Well, according to its homepage:

You're a person, not a demographic. Goombah gets that. It scans your iTunes library, finds people that like your style, and makes recommendations from their collections. Rather than cookie-cutter genre output, you get music that fits all of you.

I've tried other services that have promised to find me new music based on my tastes, but this one seems to be a lot more involved, featuring a more user-friendly interface and offering lots of free downloads. Anybody taken it for a spin yet?
