The delusion among Britney and Beyonce stans is just
Anyway,
Umber-ella >>>>>>>>>>> Poker Face >>>>>>>>>> Crazy In Love >>>>>>>>>> Toxic >>>>>>>>>> Beautiful
Umbrella sold 277K its first week available as a digital single in 2007, a record at the time. It spent 7 weeks at #1 in the US (the longest running #1 in the US that year along with Irreplaceable and Crank That), and TEN weeks at #1 in the UK. For anyone to deny that it has the most impact is just delusional.
Poker Face easily had the second largest impact out of these songs. It has gone on to sell over 6 million copies in the US and even though the video had like no impact, the song was even being sampled like the same year of its release by Kid Cudi.
Crazy In Love is honestly forgotten by the GP. I don't know why people on here think it is so big and has such a lasting impact when even Irreplaceable is bigger and more memorable by the GP. In terms of her signature hits, Single Ladies would be #1 and Irreplaceable #2. The Bey stans overrating Crazy In Love's (non-existing) impact
Toxic and Beautiful

Neither was a smash hit in the singers native countries and I'll just leave it at that
