Will NewJeans/Le sserafim be the first 4th gen group to do >50K stadium tours?

All 4th gen GGs will struggle to sell out arenas even, it's too early to talk about stadiums.

in order to pull domes , stadium, big arena outside Japan u need a big fandom. high streams simply mean gp/ casual fans. casual fans may or may not buy ur albums , or attend concerts. they may like the songs for wtv reasons but attending concerts are different since its expensive . mostly u need songs that require high performance so its not boring and they need more than 20 songs . most gg have less songs than bgs so they need cover songs ( & pay for it) to have full concert & not just fan meet. This is the reason why its easier for bg to have concerts in bigger venues- they hv bigger & more loyal fandom, more songs w/o the need for cover songs
