Hmm it's quite hard to answer it quite precisely...well, all I could say is 'Korean songs which involves lots of singing, loads of dancing, and occasionally a bit of rapping'...? I think, maybe, it's easier to say that 'songs which frequently[or all the time!] appear in Korean music TVs on weekends and something you should sing to stay at the top of the Korean music charts'! No problem for it, actually, and thank you for your feedback!
