There is no "code" that made BTS successful, the biggest mistake that all of these companies are making right now is that they are trying to replicate BTS in the first place.
never understood this narrative? Which groups are tryna replicate BTS. I haven’t seen many group used their auto-tune/vocal style but TxT (which there from the same company). Nor their clothing style. Don’t see any group (atleast top group) trying to do deeper lyrics etc.
Anytime someone says “companies are trying to replicate BTS” they mean promote in the west, which is a stupid argument because BTS didn’t invent promoting in the west.
