I've heard of such a method for the first time. I never used iPhones because I realized that there was paid music. However, I have a great alternative way that I have been using for a very long time. Instead of downloading ready-made songs, I convert a video from YouTube into an audio file and listen to the songs that I find on YouTube. With the help of the online converter, you can quickly download youtube as aac, and it is very convenient. I'm glad I came across this method, and it saves a lot of time and money.
