A rather excellent automated music recommendation and Internet radio service. Extremely simple to use, you choose the type of music you like and the site plays tracks it thinks are similar in style. While there are a number of other sites, such as www.last.fm that offer a simliar service, Pandora has an edge through its use of a rating system, allowing you to tailor the music you hear over time.

However, it must be acknowledged that Pandora has a number of limitations. you can only skip 6 times per hour, though there are a number of ways to get round this, such as opening and then closing the browser. You also can't rewind or repeat, and the number of times you can listen to a single artist is limited. Despite these, Pandora is well worth a trial.
