last.fm is another website that can help you to discover new artists. Last.fm is much more accomplished than fitit.org however fitit.org has some benefits : you don't have to listen to music on your computer to have personal recommendations, you can have instant personal recommendations as soon as you begin voting and you can filter charts and recommendations by genre and year.
