Most of you have heard about this already, but if not, check out blogmusik.net for an impressive collection(network) of ad-free music! Once you try this ipod like interface you’ll enjoy the sweet music fades between songs and custom playlists. They even have a firefox plugin for quick song finds.
Many have doubts this site will stay legal, so have your go at before it shuts down! Personally, I still use Yahoo’s Launchcast which rocks since it uses Gracenote tech to suggest songs to you much like Amazon does for books.
