I think people can always improve if they put their heart on it.
Ofc that i dont think they will become like Mamamoo or Ailee on vocal level but they need to learn how to control their breathing and have a stable voice while dancing.
For that i think kpop companies need to have their trainees/idols on treadmills and any other kind of extensive physical exercise while singing.
They also need to stop starving the idols bc they need good stamina to handle all the hard choreographies, especially on tours.
Idols should always be singing live when they rehearse. They should also release dance practices where they sing 100% live bc the more playback groups do, the more people think that is the way they sing live (so they are not only setting impossible goals but also fake goals)
Like, this should be the standard:
hmmm....I disagree somewhat
not just related to singing but some people are just not good at certain things not matter how hard one tries
for example I've had friends in HS who just couldn't understand algebra no matter how hard they tried - teachers, parents, tutors, friends - they just couldn't understand
and it may be that certain idols will never be good singers hell they might just be average/below average singers no matter how much they practice with or without a professional teacher
yes they should but at the end of the day being thin and pretty gets one more fans than otherwise (although the alternative hasn't really been tested yet lol)
what's standard is different from person to person - there is no such thing as "standard"
we must always remember an idol is an idol not a singer - they dance, act, sing, rap, mc etc etc
they are a jack of all trades and sometimes one trait exceeds the other
if their singing or dancing isn't up to one's standard they one doesn't have to consume such content - that's perfectly reasonable
different strokes for different folks
