well, we don't really TALK about kpop non stop every day. but if there's new and interesting news or songs coming out, we discuss them and it doesn't get old imo. most kpop releases come with a whole teaser cycle so there's something new to discuss every few days. here's a typical kpop release cycle.
day 1 - announcement. everyone is very pleased that that particular group has an upcoming release because you're never sure if a group won't suddenly drop off the grid and die, unless they're super popular.
day 5 - teaser image, where you see what outfits the girls are given and based on that we can speculate on what genre the song will be. (kpop groups genreally don't adhere to a rigid genre so one album they can release a house music song and then next time an electro funk song)
day 7 - another teaser image of a different group member so maybe we decide to rethink our first impression because she might have a totally different outfit
day 10 - audio teaser, could be completely misleading, but we speculate some more
day 15 - choreography teaser, where we see if might get hyped about the dance routine, if it looks exciting.
day 17 - video teaser, finally the company will release some fraction of the song and video and let us know what the song will sound like. could also be completely misleading btw
day 20 - release. this usually comes with an ep (extended play) so we have the main release and a few other songs to discuss
and usually we'll have two or three of these per month at most so it never gets old.
as for whether posting kpop GIRLS gets old, no, never. they're too cute and endearing. nobody gets tired of it
