They would be more than happy with their situation because their groups are earning big money and their profits reflect that.
The main way most new groups make money is through album sales, and I don't know if you noticed, but Nmixx sales haven't been spectacular as of now.
I never said having popular songs was bad, I was saying that being obsessed with Song Rankings is the wrong way to "value" a group especially a JYPE group where JYPark puts more emphasis on Album Sales. Wondergirls and miss A had the Top Song rankings but their Album Sales were so low it meant less money to risk on having Solo Concerts.
And twice would never be as profitable as they are without those hit songs at the beginning of their career. So yeah, song ranking still is the most important aspect to measure a group's profitability and longevity. And JYPE is not exempt from that rule.
Besides, what better way to sell a lot of albums than having a couple of hit songs?
Expectations are normal, the company's being the most important, in an area where popularity helps boost sales it's long term fans which will sustain Idol's. Creating Fan Content such as the Series that their Korean Idols release is aimed at core fans rather than the masses.
Sure, and the ther big companies do the same while being able to make catchy songs for their groups.
However, unlike SME or YGE, JYPE invested into inhouse Music Production through JYP Publishing and with their current building, they have their "Music Factory" which include 9 Dance Studios, 18 Vocal Rooms, 7 Producing Rooms, 11 Recording Booths and 2 Mixing Rooms.
After all, the music still pretty mid, with a few exceptions here and there. Maybe they should have done what all the other big companies did.
TWICE and SKz have earned hundreds of millions for JYPE but it's JYPE's system that will outlast them after those groups eventually leave. Also, I have never said that JYPE new groups are doing better than those 2 groups.
So instead of debuting a couple of a tier groups, JYPE brilliant strategy is just debuting a bunch of mid-tier ones, because that is somehow better, and surely very intentional.
And no, the system won't outlast those two groups, since they are the ones funding the majority of the groups in said system.
