Nah. As a guy who's only been listening to mainly Korean music since 2008 (before it became this huge thing internationally cuz of "Gangnam Style"), the genre has been filled with lots of crap music since 2012. Lot of 14 year old girls now listening to Kpop who only care about looks or like shit club music. I'll say straight up right now that the only Korean idol groups I listen to are from YG Entertainment (Big Bang, Winner, and maybe iKON when they debut) and Cube Entertainment (B2ST, BtoB, and sometimes A-Pink).
If they do come out to Korean songs, they should come out to songs by LeesSang, Epik High, Jay Park, P-Type, Dynamic Duo, etc.
