What I find curious about it though is that it's obviously recognizing the style - it plays 1-2 musicians from the "black" group, then circles into only playing Miller/Goodman/Rat pack and never comes back around to playing the music that I originally was trying to play. If it was behaving the way you are thinking, I'd expect it to mix the two styles.
I think the problem is that the algorithms are based on statistical probabilities from other users. I.e users who listen to X also like to listen to Y. So we’ll add Y to the queue. Then Y becomes the new reference point. I mean that is a gross simplification but essentially if your musical taste is outside of 2 standard deviations of the norm all the algorithms are gonna suck. For me they do.
If we store credit card information we need to be PCI compliant. Let’s outsource that then.
