Mess
Firework 6-7M in the USA - 10M WW
Bad Romance 5.5M in the USA - 12M WW
Bad Romance was not only more successful but by far more acclaimed, impactful etc.
Both songs were released around October / November of their respective years, yet Bad Romance made IFPI top 10 at number 2 the following year with 9.7M sales and Firework didn't even make the top 10.
Bad Romance has 2 Grammys, countless VMAs etc. The video was an event and the biggest video of the past decade according to Billboard ..
It's not even a question i just decided to provide some receipts, the only thing that people have for Firework is "it still gets played"
yeah at 4th of july, in the USA not a big deal against the global monster that was Bad Romance.
