Since people were talking about KPop being bigger than JPop in the musings/rants thread...
KPop is generally more accessible by international audiences than JPop is.
Most official channels aren't region restricted, have full videos, 1080p, and closed captions for translations.
A lot of acts also go to different countries/continents. Example: Amoeba Culture is coming to Atlanta and I'm really pissed about it.
Whether anyone likes it or not is all a matter of personal preference, but more people will find it because it's easier to find it.
