An album like B'Day happens once in a(your) career, dear Beyoncé
B'Day is by far the best album of Beyoncé, no doubts about it, she did this, then she did the good Sasha Fierce. We all remember the songs from this albums.
At that time she become a really big popstar of her generation, only Britney and few others were bigger than her, and there started her being almost worshipped in the USA but also started her decline.
4 was not a good product, then there was another wrong album, I don't even remember the title of it, and the most recent, the freaking overrated Lemonade and the other shit she did with Jay-z. In fact even from the point of view of success, her success today is big but it's always supported by giant brainwashing commercial, there's nothing genuine in it.
We all know, that, but then, every now and again one listen again B'Day and wow, that was an album. A real bomb, full of very good and powerful songs.
