I found this awesome site while going through Marina's blog. PANDORA.com (http://www.pandora.com). Simple to use website, just go there, enter the names of artists that you like, and viola it customises a "radio station" for you and plays songs of the group you Selected or from groups similar to the one that you selected. And while listening to songs, if you dont like something, just click on the guide button and delte the Song....easy...
