Great article posted on Forbes comparing the PAID versions of Pandora One, Spotify and iTunes Radio. While it appears iTunes Radio has better Audio quality it appears that Pandora One is the winner in generating music selection according to this article. While Spotify appears to be the biggest loser overall. http://www.forbes.com/sites/amadoud...s-streaming-radio-versus-pandora-and-spotify/ Another interesting article by Forbes on Pandora: http://www.forbes.com/sites/amadoudiallo/2013/10/06/pandora-radios-dominance-built-on-big-data-edge/ Personally, I have never used iTunes at all, just enabled iTunes on my 27-inch iMac and my Mid 2013 13-inch MacBook Air minutes ago. I have yet to really try iTunes radio to give it any kind of proper evaluation. I have never really got into Spotify as I found the consistency of audio quality to be severely lacking. I have been a Pandora user for many years and a Pandora One users for as long as Pandora One has been available. Since I have numerous Pandora One radio stations that have been trained through the years, I find it hard to make the jump to a new service to have to re-train a new system. What are your thoughts on all the PAID services? which do you prefer?
