I wish Apple were listening to this.
We, the customers, are responsible for the massive growth of the company. Yes, the management has done well, but without us, there would be no Apple.
So please, just allow us to turn off this ridiculous feature, if we want to. It would so easy to add a switch in Preferences, to stop this altogether. I doubt whether making people listen to random music, actually encourages them to buy, or listen to the particular track. I suppose it might. I would gladly pay 50p, or 50c a month to turn it off and have the ability to compose something myself, or add something from one of my playlists.
Come on Apple, do the right thing!
