I think part of their mission is to introduce listeners to OTHER new music they may like, based on your stated preferences, thus making it a business model that the record companies will support. Not sure how much of that is 'fishing' for record purchasers and how much is to give you an enjoyable listening experience.
Spot-on:
>Smooth jazz (enter Norman Brown and you get offerings from Boney James, Everette Harp, Rippingtons, et al)
>Reggae, (enter Black Uhuru and you get Inner Circle, Burning Spear, Julian Marley, UB40)
>Funk (Parliament gets you Gap Band, ConFunkShun, Rick James, Bootsy Collins and even the Bertha Butt Boogie by the Jimmy Castor Bunch!)
There are DEFINITELY some serious problems with the country genre, bunch of old Buck Owens-type dregs.
My Hendrix channel is also a little convoluted, too. Strange, incongruous stuff offered. Guess I need to keep rating stuff.
I AM getting a whole new appreciation for Stevie Ray, though. The guy just had the juice.
