How to buy Bitcoin on iTunes?

I've recently come across several online forums discussing the purchase of Bitcoin through iTunes, which strikes me as an unusual pairing. As a curious investor in the cryptocurrency space, I'm wondering if this is a legitimate or recommended way to acquire Bitcoin. I've heard that Bitcoin is primarily purchased through cryptocurrency exchanges or brokerages, so I'm skeptical about this iTunes method. Could you please clarify if buying Bitcoin through iTunes is indeed a possibility, and if so, what steps are involved in the process? Additionally, are there any security concerns or risks associated with this method that investors should be aware of? Thank you for your insight into this intriguing question.
