Both JK and Tae released what they wanted to release. Tae's style is sultry mood music flavored with jazz and R&B. JK, by his own admission, wants to be a huge pop star and loves pop music - like Beiber. So guess what each released? Tae - chill arthouse style R&B tracks. JK - viral-sounding catchy general public friendly banger.
What type of music dominates the charts? Yea, it's not the arthouse vibe.
