We’re done with the backgrounder and we’ve given you the must-haves, so this week on How To Collect Korean Pop Music, we dig deep – well, deep-ish; you know our usual disclaimers – into the subsets of K-pop.

And let’s be clear: when we say “boy groups” we don’t just mean the One Direction types who look good and sing in harmonies – although there are a lot of those in K-pop. Of course. There wouldn’t be a very big following if not for that, right?
