RE : Why are 4th gen groups flopping in Spotify now?

Why are a lot of 4th gen groups regressing in terms of spotify streams? Their songs are falling off fast or not debuting on the chart at all. Txt, Ateez, Enhypen, Aespa and now the 4th gen queens of Spotify Itzy.

This looks even worse considering songs that are extremely hated like O.O and wa da da made it into the charts yet songs by some top groups couldn't make it at all. What is happening?
