4 sold well over 1 million (in the US alone) & 3 million WW. Not a smash, but not a flop either. It was just a fall off from I Am... Sasha Fierce which was very huge era for her.
But still, 4 was her best album at the time & she gave her fans so many good songs they'll appreciate for the rest of her career. LOT has excellent recurrent airplay & would've been a hit in today's music market. 2011 was all dancepop & nothing from 4 was really accessible at the time. Only End of Time, but she handled that song horribly & didn't bother releasing it. Countdown was kinda snubbed by the GP too.
Wow so much backlash
