f(x). I like Momoland but they don’t have any number over f(x). You should know better Drew_B, you are the fan here.
I checked and Momoland total album sales is like 70k whereas f(x) is like almost 600k.
Bboom Bboom is probably a bigger hit than any other f(x) song but but it’s their only successful song with Bam that did not perform badly but was just a moderate hit. f(x) had multiple hits and songs that charted pretty well. Their success was less impressive than Momoland’s peak but way more constant.
It was just expected than one was going to perform better than the other. f(x) have a lot of quality, Momoland too but they already outdid their nugu career with Bboom Bboom whereas f(x) had a whole SM behind them. The SNSD vs Twice comparison makes more sense.
