I am a fan of her and I think manic is the best album of the year besides Chromatica
BUT
I am not blind.
It's true that it's one of the most streamed albums of 2020, but more than half of those streams come from Without Me. And now she did the fraudery by adding Be Kind, which has way more streams (and is growing faster) than any song on Manic (sans WM).
In conclusion yes, it's nearing 2,5B but 1,5 come from two songs, one of which doesnt even have her as the lead artist. Truly an "Heaven & Hell outstreamed Chromatica teas"
