Even if you don't know what you are looking for - gnod will find it.
Gnod is a self-adapting system that learns about the outer world by asking its
visitors what they like and what they don't like. In this instance of gnod all
is about music. Gnod is kind of a search engine for music you don't know
about. It will ask you what music you like and then think about what you might
like too. When I set gnod online its database was completely empty. Now it
contains thousands of bands and quite some knowledge about who likes what. And
gnod learns more every day.
