"Go to the page of your number one artist, and follow the link of it's number one similar artist, then repeating that for this artist and so on, noting down each artist as you go. Do this until you've got to 50 artists (not including your number one). If you get any repeats, just go to the second similar artist or the nearest one that you haven't already had."
My top artist for this week is Madonna :
7.The Pussycat Dolls
