i have the iphone 6 & current update 9.1 version... my issue is i cannot add songs to my wish list anymore. previosly I would tap the price, "$1.29" for example, of song to have "add to wish list" option; however it directly goes to the option to "buy song" when i tap price now.
If the songs allows you to add it to a wish list (some tracks might be album or single only) then you should have a 'share' icon (a square with an upward pointing arrow ; on my 5S it shows at the top the screen on iOS 9.1) - tap on that and you should get a popup with a series of options, one being 'add to wish list'.
The price button is the buy button, as far as I know that's all it ever allowed you to do
