I recently bought some new speakers for my computer based on recommendations: Klipsch ProMedia 2.1 THX. I find them excellent but I must admit I am not a very discriminating audiophile. I also found a nice new site to take advantage of the new speakers: Jango. Essentially this site lets you select a list of artist you like. They then play music by those artist and other artists like by those that like your list (I imagine). There are no ads. My guess is they make money when you buy music through the site (and probably have, or will get) special payment to promote some artists.
