I believe Apple has always put featuring artists in ()'s and []'s, but it's been a long time since I've used iTunes to buy music. The problem is that a track like, "My Love" which fits elegantly on the display screen, will then not only have to scroll a couple of times to fit all the featuring info, but it'll look horrible as you browse through your list of songs whether you're on an iOS device or on the computer. That album in particular has a lot of complexity in the track naming to begin with, and it's not the only one.
