You've been tasked with creating a dream pop supergroup - comprised of any pop girl, guy, band member, etc from past or present.

Let's say you can select anywhere from 3-6 members.

Who would they be?
What would the group be called?
What kind of music would they make?

You can give as much or as little detail as you want - for those eager, you may even suggest who has what role in the group, etc.
