iTunes sends tons of data to a radio-activity URL

Hi Apple community,

I have noticed a strange network spike when my computer is totally idle. That means, not using it at all. I tried to figure out what it is. The resource monitor opened, I found out that it's iTunes, sending some data with ~5 MBit/s every 10 seconds. I tried to find some settings in iTunes, but I couldn't find anything.

So I installed wireshark to find something and I got a new connection every 10 seconds that sends encrypted data (TLS 1.2) to radio-activity.itunes.apple.com. Sadly, I wasn't able to get any information about what it's uploading there because of the encryption.

The amount of data is 130 MB in 10 minutes, what's 780 MB in an hour and 6,2 GB on a 8-hour-working day. That's very much data consumption for nothing - it's only open and idle, no music playing or anything. When I close iTunes, the network spikes stop immediately.

Does anyone have the same issue? At home in WiFi it's not a big deal but on the road with mobile network it's extremely annoying. I don't see anything like this on my mac (just tried to find something similar in the activity monitor while running the music app).

My system is a windows 11 (22H2) computer with iTunes 12.12.9.4 running. I'm using Apple Music and iTunes Match services.
