Okay, I answered my own question regarding the iKon track, "Just Go."

.............*rips hair out of skull and screams to the heavens*...............

What in the actual ?  I have a huge problem with this whole thing of certain songs only being released in certain formats.  Mainly because as an American, that means that if I want to own this song, I have to buy the Japan cd from the internet and spend almost $100 doing so. I feel like this alienates the international market since I don't know many people that would put down that kind of money for a cd after downloading the iTunes just to get one song.  The same issue presents itself with the Japan albums for BigBang.  Those albums are only available to buy as a cd from most likely Ebay, and some of my fave BB tracks are from their Japan releases.  Then there is the case of GD releasing an album digitally but then allowing one or two tracks to only be released with the physical cd, like Window or the full Korean version of Black.  I'm sure they probably assumed that us English speakers wanted to hear Sky Ferrera's heavy breathing over the chorus because it was in English, but quite frankly, if we really cared that much about it, would we really be listening to K-pop to begin with?  Sky's ty vocals aside, the lyrical content was simply better in Korean over the English version (seriously, who wrote the English chorus? Because it's kind of terrible and it detracts from how good the rest of the song is)

This whole rant is so discombobulated, but I think you get the point.  I just think that if the Korean music industry really wants to continue making headway in the international market, then ALL of the music should be easily available.  Going through so many loopholes is just annoying, and it makes it not worth it to bother.
