Let's be honest for a moment ...
... when you install software that plays music. And this software has a function that suggests other music from the internet shop associated with the software based on the currently playing track. Are you really surprised to hear that this software transmits data of the currently playing song to the store? Regardless of what the software is called?
Sorry, but I really don't understand this somewhat strange excitement. The function in question cannot be realized without communication with the store - it is to be expected that data will be transmitted for this purpose, after all, data also comes back.
If iTunes always transmitted the data, even when this silly suggestion window is not open, there would be reason to be excited. But as it is, I find the whole thing quite silly - you are upset that a function does what it says it does. But you buy your music from a store that records your credit card, your general music taste, your movements - and grants you only limited rights for your purchased music. But that's okay - as long as it doesn't transmit your currently playing track - which you probably slap onto your websites via script anyway.
But otherwise, are you still doing well, yes?
