I don't get why y'all think Ariallah is going to flop just because Adobe is slaying right now. That Bieber track is doing really well and it got released on the same day, and her last lead single almost dethroned Happy from #1 on Billboard, not to mention all of the hits she's had since.
The real queen of vocal talent will be coming with her #2 peaking smash that will END our faves' careers.
Yeah, 1D has lost this battle, but at least they'll always have a tour that's grossed over 300 million -- something Bieber won't be able to claim, never.
At the end of the day, no one outside of forums/Twitter/music labels gives a **** about numbers and sales. What really shows a legacy is the mark you leave on the public, and 1D have left close to none outside of What Makes You Beautiful. Hell, ask a grown adult to name all five of them and you'll be lucky if they can name even two (bet one of them will be the one who's no longer even part of it).
They literally have nothing but numbers to their names. A more well-known Jonas Brothers in that they thrive entirely off of their fan base rather than the actual public, which is why their discographies remain unknown.
