21 > TFM > BTW/Recovery/RED > TD / Loud = Unorthodox Jukebox / Doo woops = TTAL
Does TFM count tho ?
TFM EP sold 5.5M in 2010, TFM Deluxe (TFM + TF) sold 2M-3M in 2010
TFM sold 1M in 2011
Which is 8.5M in those 3 years, making it easily the 2nd biggest era after 21. But are you talking about albums released this decade, or just most successful this decade .. ?
Why are people forgetting TFM when it sold more than BTW, Red etc. in the 10s
