All the singles are charting plus Peacock. Death at the fact Peacock is higher than TOY and WUIV. It's surely going gold by itself, if we get a video it could go platinum or 2X.
Combined ET is probably in the top 100. I can't at Firework's longevity.

I bet if it were discounted it would be in the top 30 and re-enter the hot 100.
