Top music artists from unnamed portal site

A friend sent me this internal list of top music artists from one of the large portals: This is a list of most requested audio streams, in order of request
50 Cent
Hilary Duff
Luther Vandross
Christina Aguilera
Black Eyed Peas
Justin Timberlake
Rolling Stones
Mariah Carey
The utter blandness of this list shows that the public wants what it knows. No surprises there.
