There has once been a discussion, about the use of "feat." before. In which one argued, that using "XXX" feat. YYY may be regarded, as the YYY singing a minor part. (See talkpage of halyosy.)

(I suppose, before, we used "ZZZ x YYY"; ZZZ and YYY being utaite?)

So writing both names, may be a sign, that both parts are equal.

In the case, they are not equal (e.g. when one utaite only sings harmony, while the other sings the main vocals), the parts are usually stated after the name ("XXX" feat. "ZZZ" (harmony) and "YYY" (main vocals)). (E.g. collabs by kradness and Reol.)

So in that case, having "XXX" feat. (harmony) "YYY" (main vocals) would not only look weird, but be kind of illogical. While if the format instead was "XXX" (harmony) feat. "YYY" (main vocals), it wouldn't make much sense either. (Since the bracket after the title is supposed to be for something else.)

Sure, those things are not the common case, but it's better to keep things consistent.

(Not to mention, we also have some group pages, on which all singers are credited.)

I don't really understand your point with the artist o.O

We only put singers after the "feat.".
