Like for GGs we have hits like Dalla Dalla which probably is the biggest GG hit among the 4th Gen. Other than that, groups like (G)I-DLE and IZ*ONE also have moderately popular hits especially in 2020.
But it seems like BG doesn't really have hugely popular songs? I mean historically on average GG songs tend to be more popular than BG songs but even so among 2nd Gen and 3rd Gen there is quite a list of popular hits.
I might be wrong about this though because I don't exactly know how popular the songs are. I keep seeing posts last time on how bad 4th Geb BGs chart despite their huge physical sales.
So back to the question, what are some of the biggest 4th Gen BG hit?
