so some groups with the most songs
IU - 8 songs
BTS & Twice - 5 songs
BP - 3 songs
Wannaone - 2 songs
MMO, RV, Btob, Winner & Ikon - 1 song
Its always interesting to me that exo is arguably the 2/3rd biggest bg digitally for the 3rd gen but they dont have any certs like others do
Wanna One don't get mentioned enough. They did so damn well when they were active.
