James turned me on to a cool (and free!) music site called Pandora. You start by plugging in the names of artists or songs you like, and they compile a streaming "radio station" just for you. It's a great way to find new music that is similar to the stuff you already like. You get to rate each song that plays, thumbs up or down, which helps them fine-tune your playlist. Fun, and a really nice interface to boot.
