Buying single song without subscription
Apple Music requires a subscription and is difficult to buy a single song, but a kind of hidden app called iTunes store with a blue icon and a white star inside works the way the older iTunes app worked and allows you to search and buy a single song for $1.29 and it adds it to the Apple Music library so you own it. For some reason they took one app and made two apps, probably just to make people buy a subscription
