My guess: take jazz fans on one hand, and Justin Bieber groupies on the other hand. The jazz fans would in general appreciate way more the DW service than the Justin Bieber ones. Why so? Because the 'vector' that describes a jazz fan's playlist is probably much more specific and 'unique' than the vector of an heavily standardised MTV-based playlist. Everyone gets the recommendations they deserve...

I mean there are artists that I like as an exception because they're sentimentally meaningful to me. I don't want to hear other music, even in that genre. Bieber fans might only be fans of Bieber's music and not other pop.

I wonder if anyone's studied this. Maybe it's not a common sentiment...
