Marketing 101
BTS and its members have given a lot of artists they have collabed with their many firsts. Most notable is Savage Love. Even when it was viral and stolen by itself, they needed BTS on the remix to get a #1 on BB HOT 100. And now surprisingly it's a mini hit song even outperforming whole groups on Melon.
If anyone works in marketing will know just who hard carries. From selling out festivals as soloists to selling 400K concert tickets in less than 30 mins, people see the marketing value of BTS and that is why they are ranked so high year in and year out.
I have a small background in marketing so I would love to know how people in the industry sees their brand.
