Now unless Adele drops, really she's the only 1 capable of surpassing 10M global units in a few months.
Ed sheeran & Drake & Kendrick Lamar & possibly Rihanna will all drop albums in 2021 but honestly like Taylor in 2020, I believe they've all peaked with their previous albums.
I'll be genuinely surprised if any of these heavyweights pull 7M units within the year (I see some of them pulling 4M-6M tho with majority of sales from the US)
I think a BP album (should they release the 2nd full album in 2021) can do over 7M global units in 2021(they pulled over 5M in 2020)
So really it could very well be a BP v BTS situation or those 2 can occupy the 2nd/3rd position with Adele at #1
Y'all can probably bookmark this thread & reference it later on should BP drop another LP this year.
