I really like the Cookie Run franchise. I don't know anything about BTS aside from being a "personality band" akin to the Spice Girls or boy bands where the members' personal lore is just as important as the music that is produced by other people. It's pretty easy to understand why they had rabid fans years ago online, as they were mostly teen girls, the demographic for these types of bands.
Cookie Run Kingdom has been doing a 3 month crossover event, including a rhythm game. I love rhythm games, so in order to be the best I've had to listen to a lot of BTS to get the stepcharts down. So let's break down these songs from someone detached from the kpop ecosphere (except BOA, she rules).
We'll be covering the sounds, the video (if applicable), and the stepcharts featured in CRK for the 5 songs featured in the game I've listened to to death by now, in the order the game presents them to you.
