Last.fm system will learn your musical taste and will progressively serve you music you'll probably like. Then, you can find people who have the same musical taste as you and listen to their stream.. At any moment, you can access all streams you already listened to, to get more
info, order CD from Amazon and so on.
For old web users, this will probably remind you of Firefly, before they were bought by Microsoft.
In short, it is THE online radio I've been looking for a very long time.
Try it, you'll love it.
