Hmm, that's weird, I've been struck by the discover weekly' she ability to serve up song after song I've never heard before, maybe two or three out of the thirty are familiar on average.

But it's mainly just a discovery service. Since I tend to like idiosyncratic music, it works well for me in a way that other services never did. Pandora in particular always played the most obvious, well known tracks, based on the starting point.
