Assuming BP leaves YG or disbands, will YG fall out of the Big4? And will they follow in the DSP footsteps? DSP used to have some of the most successful kpop acts (and were SM's competition) with Sechskies, Fin.K.L and KARA, but have since fallen from grace so hard barely anyone remembers them.
I don't really see YG boygroups carrying a mid sized company, let alone a Big4 one
